    THOMPSON, Circuit Judge.           The defendant, Damien Corbett,
    raises   three     issues    in     this   appeal    from    his   conviction    of
    conspiracy to distribute and possess with intent to distribute
    oxycodone    and    oxymorphone.           Corbett   first      argues   that   the
    government's evidence was insufficient.                Somewhat relatedly, he
    contends that the district court committed plain error in its
    response to a question from the jury.                Finally, he asserts that
    the court erred in imposing a sentencing enhancement for the use
    or attempted use of a minor in the commission of the offense, see
    U.S.S.G. § 3B1.4.        We affirm.
    BACKSTORY1
    Back    in      2014,     as    part     of     a    drug-trafficking
    investigation in North Berwick, Maine, law-enforcement personnel
    orchestrated several controlled buys of oxycodone pills2 from two
    dealers, Taysha Gillis, who was then eighteen years old, and
    Kenneth Gerrish.      On December 16, 2014, Gillis and Gerrish were
    arrested soon after the final controlled buy. Police also executed
    a search warrant for Gillis's residence that same day and found
    1 Because Corbett challenges the sufficiency of the evidence,
    we recount the facts in the light most favorable to the government.
    See United States v. Ponzo, 
    853 F.3d 558
    , 566 n.1 (1st Cir. 2017).
    2 Oxycodone pills are sometimes referred to by their brand
    name, Percocet.
    - 2 -
    over 550 oxycodone pills, over 350 oxymorphone pills,3 and thirty-
    seven Suboxone pills4 in two safes in Gillis's bedroom closet.
    Meanwhile,   police    questioned   Gillis   and   Gerrish
    separately.   Gillis quickly came clean:   She removed eighty-seven
    oxycodone pills from her shirt and identified Corbett as her source
    for the pills she was peddling.5    Armed with this knowledge, law
    enforcement decided to set up a meeting between Gillis and Corbett.
    Now in full-cooperation mode, Gillis — wearing a wire to
    record the encounter and possessing $3,000 in government-supplied
    prerecorded buy money — met with Corbett a few days after her
    arrest; the ostensible purpose of this meeting was for Gillis to
    pay Corbett money for pills that he had "fronted" her.6      The two
    met inside Corbett's car.7   After some brief chitchat, Gillis and
    3 Throughout the record, the oxymorphone pills are referred
    to by their brand name, Opana.
    4 Although the record is silent on this point, we have
    previously explained that "Suboxone is a prescription medication
    that is used to block the effect of withdrawal from opiate
    addiction." United States v. Fleury, 
    842 F.3d 774
    , 777 n.1 (1st
    Cir. 2016).
    5Like Gillis, Gerrish also identified Corbett as the supplier
    of the pills he was selling.
    6 For those not hip to drug-dealing lingo, drugs are "fronted"
    when a supplier gives them to a drug dealer on credit with the
    understanding that the dealer will pay for them once he or she is
    financially able to do so.
    7 When Gillis entered Corbett's car, he was listening to a
    talk show on the radio. Because Corbett kept the radio on for the
    entirety of their meeting, the recording of what was said in the
    car is unintelligible in some places.     We piece together the
    - 3 -
    Corbett discussed their mutual mistrust of Javier, the then-
    boyfriend of Gillis's mother; Corbett had previously expressed his
    concern to Gillis that Javier, as a Coast Guard employee, might
    impede their pill-distribution scheme in some way.                 Because of
    this concern, Gillis proposed that Corbett take back some Opanas
    that she had been unable to sell:         "I don't trust Javier either.
    That's why I think you should get the Opanas really soon . . . ."
    Corbett responded:     "All right, I will.           I will pick them up,
    uh . . . tomorrow or the day after."         Following this exchange, and
    because Corbett was concerned that the pair's cellphones might be
    tapped, he suggested that Gillis put both phones in her car so
    that they could continue their conversation in his car.                Gillis
    complied with this directive and then returned to Corbett's car.
    Later in the conversation, Gillis asked Corbett, "What
    is it I owe you again?" When Corbett responded "Twenty-six fifty,"
    Gillis pushed back, "I thought it was twenty[-]five sixty for some
    reason."   Corbett replied: "I have to think.        It might be."     Gillis
    then offered to pay Corbett $2,560 and suggested that she had
    "extra in case you wanted to give me anything else."                  Corbett
    accepted   the   $2,560,   and   responded    that   he   didn't    have   any
    oxycodone pills to sell Gillis at the moment.             Corbett then told
    Gillis, "[T]omorrow I will come back," which she understood to
    substance of the encounter from the intelligible portions of the
    recording and Gillis's trial testimony.
    - 4 -
    mean that he would pick up the Opanas the next day.             After the
    money switched hands, Gillis told Corbett that she still had some
    Suboxone pills and did not want any more of those pills:             "I'm
    gonna like keep those and continue to try to get rid of the rest
    of those but I don't want any more of those."        Corbett responded,
    "Alright."     The conversation eventually ended, and Gillis left
    Corbett's car.
    At this point, multiple officers converged on the scene,
    and Corbett was arrested. In a search of his vehicle, police found
    the $2,560 in prerecorded buy money in the center console, as well
    as an additional $3,843 underneath the seat.         When questioned by
    police, Corbett insisted that he and Gillis "were just talking."
    Police asked Corbett about the money found in his car, and he
    answered that it came from "a settlement";8 he did not mention that
    Gillis had just paid him.
    A federal grand jury indicted Corbett on one count of
    conspiracy to distribute and possess with intent to distribute a
    mixture   or   substance   containing    oxycodone   and   a   mixture   or
    substance containing oxymorphone, in violation of 21 U.S.C. §§ 846
    and 841(a)(1).    The indictment alleged that the charged conspiracy
    8 At the time of the interrogation, Corbett had recently
    "received a sum of money" as part of an insurance settlement for
    a fire loss.
    - 5 -
    ran from "approximately June 2013 through and until December 16,
    2014."
    Both Gillis and Gerrish, among others, testified at
    Corbett's trial.9   Gillis told the jury about the evolution of her
    relationship with Corbett.   She first came in contact with Corbett
    through Facebook when she was thirteen years old.   After "[m]aybe
    a month or a couple of months" of communicating through Facebook,
    the two met in person at the home of Gillis's friend.         On that
    occasion, Corbett gave Gillis some money and asked her "to get him
    weed."    Gillis left and did as Corbett instructed, but when she
    returned with the goods, Corbett had already left the house; he
    told Gillis to keep the newly purchased merchandise for herself.
    Corbett and Gillis continued to occasionally see one another,
    typically at Gillis's home.    On one of these occasions, Corbett
    provided the underage Gillis with alcohol.
    Eventually, the relationship between Corbett and Gillis
    entered the realm of oxycodone trafficking.    It all started when
    Corbett and Gillis decided to ask Gerrish if he could obtain
    oxycodone pills from his father and sell them to Corbett.10    Gillis
    9 By that point, Gerrish had pled guilty to conspiracy to
    distribute oxycodone, and Gillis had pled guilty to conspiracy to
    distribute both oxycodone and oxymorphone.
    10 When asked "who brought up the idea," Gillis responded,
    "Um, both of us [i.e., Corbett and Gillis]."
    - 6 -
    asked Gerrish, and Gerrish obliged, obtaining the pills from his
    dad and selling them to Corbett for a profit.
    After this first exchange, Corbett told Gillis that he
    could obtain oxycodone pills (from some unknown source who was not
    Gerrish's father) for $22 per pill and that she could sell them
    for a profit.      Gillis agreed to that arrangement, and, about a
    month later, Corbett fronted her the first delivery of pills. Over
    the next two years until Gillis was arrested, Corbett continued to
    deliver oxycodone pills for Gillis to distribute.          The frequency
    of the deliveries varied; sometimes they occurred on a weekly
    basis,    and   sometimes   monthly   drop-offs   were   made.   Corbett
    continued to front Gillis pills on occasion. Gillis also testified
    that Corbett set the price that she paid for the pills; she once
    asked Corbett how many pills she'd have to purchase in order to
    get a cheaper price, and Corbett responded, "Too many." And Gillis
    never obtained a cheaper price from Corbett.             In addition to
    oxycodone, Corbett also supplied Gillis with "Suboxone, Opanas,
    Dilaudid, [and other] pharmaceuticals."11
    Gerrish also testified against Corbett.          He told the
    jury that he agreed with Gillis to sell oxycodone pills that he
    would purchase from her.     Gerrish also explained that he sometimes
    11With respect to the oxymorphone pills in particular, about
    two months before Gillis was arrested, Corbett told her that she
    could make more profit selling oxymorphone pills than she could
    selling oxycodone pills.
    - 7 -
    was present when Corbett delivered pills to Gillis.                 On those
    approximately five occasions, Gerrish saw Corbett hand Gillis "[a]
    baggie with pills in it."       On cross-examination, however, Gerrish
    acknowledged that, when he was interrogated by police after his
    arrest, he denied that he had seen any hand-to-hand exchange of
    pills between Corbett and Gillis.          He explained, "At that time I
    denied a lot of things."
    After the government rested its case, Corbett moved for
    a judgment of acquittal under Rule 29(a) of the Federal Rules of
    Criminal Procedure, arguing that the evidence was insufficient.
    The district court denied the motion.           In his closing argument,
    defense    counsel   attacked   the   credibility   of   both     Gillis   and
    Gerrish.      Gerrish,   defense      counsel   stressed,   had    testified
    inconsistently with what he initially told investigators about
    observing pill exchanges between Corbett and Gillis.                 Defense
    counsel painted Gillis as a liar who was seeking to falsely pin
    the blame on Corbett in the hopes of receiving leniency for her
    drug-dealing ways.     Finally, defense counsel also emphasized that
    police did not find any drugs on Corbett or in his car when they
    arrested him.
    In its final charge to the jury, the district court
    instructed the jury on the elements of conspiracy, and told the
    jurors that they should consider the testimony of the cooperating
    witnesses, Gillis and Gerrish, "with caution" because "[t]hey may
    - 8 -
    have had reason to make up stories or exaggerate what others did
    because they wanted to help themselves."               At the conclusion of its
    instructions,     the   court     asked      counsel    whether   they   had   any
    objections   or   additions       to   the     instructions   just    delivered;
    defense counsel responded that he did not.
    During their deliberations, the jurors sent multiple
    notes to the judge, two of which are relevant to this appeal.                  The
    first note, which was submitted to the court approximately two-
    and-a-half hours after deliberations began, asked: "Can you please
    advise us regarding inability to reach a verdict?                 Both sides are
    adamant." The court responded, "In response to your note, I advise
    that you again review the evidence and my instructions and continue
    to deliberate."    Defense counsel informed the court that he had no
    objection to this response.
    The     second   note    from      the   jurors   read:     "Does    the
    intention of the defendant to pick up the drugs ([O]panas) [from
    Gillis's home] as evidenced in the audiotape fall within the scope
    of the indictment charges?" (Asterisk omitted.) After the parties
    initially disagreed on how to respond, the district court briefly
    set forth his intended response.             Both before and after the court
    discussed its response, the judge told the parties, "I'm not wedded
    to this." The court proposed the following response: "In response
    to your note (Court Exhibit 6) and to answer your question, you
    need to determine if the conspiracy charged in the indictment
    - 9 -
    existed, what was the scope and purpose of that conspiracy, and if
    the defendant willfully joined the conspiracy based on the evidence
    of his own words or deeds."    When the district court solicited the
    parties' views on its proposed response, defense counsel stated,
    "I think it restates the instruction already given, so I have no
    problem."
    The   jury   ultimately   found   Corbett   guilty.    The
    presentence investigation report (PSR) recommended a two-level
    enhancement under U.S.S.G. § 3B1.4 for Corbett's use of a minor,
    Gillis, during the conspiracy.    Corbett objected to this aspect of
    the PSR.    The district court applied the enhancement, accepting
    the government's argument that the evidence showed that Corbett
    had groomed12 Gillis to distribute drugs for him.            The court
    sentenced Corbett to a term of 100 months of imprisonment. Corbett
    timely appealed.
    ANALYSIS
    A.    Sufficiency of the Evidence
    We first address Corbett's argument that the evidence
    against him was insufficient.     Because he preserved the issue by
    filing a motion for judgment of acquittal, our review is de novo.
    See United States v. Gonsalves, 
    859 F.3d 95
    , 110 (1st Cir. 2017).
    12We'll discuss the district court's grooming conclusion in
    more detail below, see infra Part C.
    - 10 -
    In assessing a sufficiency-of-the-evidence claim, we
    view the evidence in the light most favorable to the government,
    draw all reasonable inferences in its favor, and ask whether a
    rational factfinder could have found each element of the charged
    offense beyond a reasonable doubt.                   See 
    id. at 110-11;
    United
    States v. Rivera-Ruperto, 
    846 F.3d 417
    , 432 (1st Cir. 2017).
    Additionally, we "must defer all credibility judgments to the
    jury," 
    Gonsalves, 859 F.3d at 111
    (quoting United States v.
    O'Brien,     
    14 F.3d 703
    ,   706     (1st    Cir.    1994)),     "drawing   all
    credibility choices in the government's favor," United States v.
    Morosco, 
    822 F.3d 1
    , 7 (1st Cir. 2016), and disturbing "only those
    evidentiary       interpretations       .    .   .    that    are    unreasonable,
    insupportable, or overly speculative," United States v. Serunjogi,
    
    767 F.3d 132
    , 140 (1st Cir. 2014) (internal quotation marks
    omitted) (quoting United States v. Hernandez, 
    218 F.3d 58
    , 64 (1st
    Cir. 2000)).      Given the manner in which we must view the evidence,
    it's no surprise (and no secret) that a sufficiency challenge is
    oftentimes a bit of a longshot.              See 
    Rivera-Ruperto, 846 F.3d at 432
    (explaining that sufficiency claims are "rarely successful"
    (quoting United States v. Moran, 
    984 F.2d 1299
    , 1300 (1st Cir.
    1993))); 
    Morosco, 822 F.3d at 7
    (explaining that "[s]ufficiency
    arguments seldom         succeed"); United States v. Correa-Osorio, 
    784 F.3d 11
    ,   26   (1st    Cir.   2015)      (explaining      that   "[s]ufficiency
    challenges rarely succeed"); United States v. George, 
    761 F.3d 42
    ,
    - 11 -
    48 (1st Cir. 2014) (explaining that "a sufficiency challenge is a
    tough sell" (quoting United States v. Polanco, 
    634 F.3d 39
    , 45
    (1st Cir. 2011))).
    The government needs to prove three elements beyond a
    reasonable doubt to secure a conviction for conspiracy under § 846:
    "(1) a conspiracy existed; (2) the defendant had knowledge of the
    conspiracy;     and     (3)   the   defendant      knowingly       and   voluntarily
    participated in the conspiracy."               
    Rivera-Ruperto, 846 F.3d at 432
    (quoting United States v. Maryea, 
    704 F.3d 55
    , 73 (1st Cir. 2013)).
    The   third    element     requires      the    government   to     show   that   the
    defendant "intended to join the conspiracy and that he intended
    for its goals to be accomplished."               United States v. Paz-Alvarez,
    
    799 F.3d 12
    , 25 (1st Cir. 2015).                 Viewing the evidence in the
    requisite verdict-friendly manner, the government's evidence in
    this case was plainly sufficient.
    Sufficient      evidence    was    presented    to    show   that   the
    charged conspiracy existed.           See 
    Rivera-Ruperto, 846 F.3d at 432
    .
    Based on the testimony of Gillis and Gerrish, a rational juror
    could have concluded that an oxycodone-distribution conspiracy
    existed where Corbett would supply the oxycodone to Gillis, who
    would   then     sell     the    pills     to    others,     including     Gerrish.
    Additionally, Gillis testified that, about two months before her
    arrest, Corbett told her that she could make more of a profit
    - 12 -
    selling oxymorphone pills, Gillis "agreed to see if [she] could
    sell them," and she sold "1 or 2" oxymorphone pills.
    The testimony of these two witnesses also amply supports
    the second and third elements of the charged conspiracy — that
    Corbett knew of the conspiracy and knowingly and voluntarily
    participated in it.    See 
    id. Gillis testified
    that Corbett was
    her source for the oxycodone and oxymorphone pills.                And she
    testified that, over a two-year period, Corbett continued to
    deliver oxycodone pills to her on either a weekly or a monthly
    basis and that the average number of pills Corbett delivered each
    time increased during the course of the conspiracy.            Gillis also
    told the jury that Corbett supplied her with oxymorphone pills on
    one occasion.    Like Gillis, Gerrish told the jury about the times
    he witnessed Corbett delivering pills to Gillis.         Finally, Gillis
    testified that Corbett fronted some of the pills that he delivered
    to her.   See United States v. Bedini, 
    861 F.3d 10
    , 15 (1st Cir.
    2017) (explaining that fronting drugs can constitute "an act of
    trust   that   assume[s]   an   ongoing    enterprise   with   a   standing
    objective" (quoting United States v. Ortiz-Islas, 
    829 F.3d 19
    , 25
    (1st Cir. 2016))).
    Corbett's knowing and voluntary participation in this
    conspiracy was also established by Gillis's testimony about what
    - 13 -
    transpired during the recorded conversation in the car.13             When
    Gillis asked Corbett to pick up oxymorphone pills from her, he
    agreed to do so.    Additionally, after a brief exchange about the
    precise dollar figure, Corbett accepted $2,560 from Gillis for a
    debt that Gillis owed him, and Gillis told the jury that this debt
    was for oxycodone pills that Corbett had previously fronted her.
    Finally, Corbett's conduct during the conversation with Gillis
    betrayed a fear of being overheard while talking to her about the
    conspiracy;   he   played   his   car   radio   loudly   throughout   the
    conversation, and, worried that their cellphones might be tapped,
    he instructed Gillis to put the phones in her car so that they
    could safely talk in his car.              Cf. 
    George, 761 F.3d at 51
    (explaining, when considering evidence that defendant expressed
    over the phone his unwillingness to engage in illegal activity,
    13 Even if we accept Corbett's position that no conspiracy
    existed at the time of the recorded conversation because both of
    Corbett's coconspirators were cooperating with law enforcement,
    the recorded conversation (and Gillis's testimony about it) was
    still admissible. See United States v. Fanfan, 
    468 F.3d 7
    , 11-12
    (1st Cir. 2006) (explaining that evidence of recorded conversation
    between defendant and coconspirator who had, unbeknownst to
    defendant, been arrested and was cooperating with law enforcement
    at time of conversation was admissible in conspiracy prosecution);
    cf. 
    Ortiz-Islas, 829 F.3d at 27
    (affirming admission of evidence
    of post-indictment sting-drug transaction because evidence "'was
    closely linked in time to the alleged conspiracy and proved the
    identities and relationships of the conspirators'" and "evidence
    of the final, faux deal merely illuminated what had been going on
    among the relevant parties for over a year, a course of conduct
    that was firmly shown through overwhelming evidence including co-
    conspirators' testimony" (quoting United States v. Niemi, 
    579 F.3d 123
    , 128 (1st Cir. 2009))).

    that "a logical jury could also conclude that [defendant] did not
    like    talking   shop    over   the    phone    and    so   sprinkled     in   words
    suggesting his unwillingness to do anything illegal just in case
    the police were listening in").
    Perhaps      in   recognition       of   the     testimony     of   these
    witnesses, Corbett appears to concede that, if the jury believed
    Gillis and Gerrish, the evidence was sufficient.                     But wait, he
    says:    "The jur[ors] could not have unanimously agreed on their
    credibility," he tells us, "because [of] the notes to the court
    sent out during deliberations."             Corbett appears to support this
    argument with the following reasoning.                 The first note, in which
    the    jurors   indicated     that   they     were   at    an    impasse   in   their
    deliberations,     suggested     that    at     least     some   jurors    were   not
    convinced beyond a reasonable doubt that Corbett was guilty of the
    charged pill-peddling conspiracy.             The second note showed that the
    once-divided jurors were now focusing on the audio recording of
    the December 19 meeting with Gillis and Corbett.                     Weaving these
    two strands together, Corbett insists that the jurors must have
    found him guilty of a conspiracy solely based on the recorded
    conversation, which occurred at a time when Gillis was acting as
    a government agent and, therefore, could not be a conspirator as
    a matter of law.      This line of argument, although creative, cannot
    carry the day.
    - 15 -
    Corbett places far more weight on the juror notes than
    they can reasonably bear.           The second note tells us only that,
    when the jurors wrote the note, they were then focusing on the
    recorded conversation.          Contrary to Corbett's position, that note
    in no way suggests that the jurors had rejected all of the other
    evidence in the case and had discredited the testimony of Gillis
    and Gerrish.    Similarly, the first note suggests only that, when
    the   jurors   wrote   that      note    after    less   than   three   hours   of
    deliberations, they were not yet all on the same page with respect
    to Corbett's guilt or innocence.            As was true for the second note,
    nothing in the first note suggests that the jurors in the end
    rejected the testimony of Gillis and Gerrish. Therefore, we reject
    Corbett's argument that the two juror notes demonstrate that the
    jury found these two witnesses to be not credible.
    Perhaps     as   a    fallback    to   his    primary   insufficiency
    argument, Corbett also offers discrete reasons why the testimony
    of both Gillis and Gerrish was, in his view, suspect.                       Both
    witnesses, he points out, began cooperating only after they had
    both been caught red-handed with a cache of pills.                 Additionally,
    Corbett highlights the about-face in Gerrish's story; although he
    initially told police that he had not observed any hand-to-hand
    exchange of drugs between Corbett and Gillis, he testified at trial
    that he had, in fact, seen such exchanges.                  And Gillis was no
    saint, either, Corbett insists.             He emphasizes that, even after
    - 16 -
    Corbett was removed from the picture on account of his arrest,
    Gillis went right back to her drug-dealing ways, and this time
    heroin replaced oxycodone as the hot commodity.
    Although these seeds of doubt might have stood some
    chance of finding fertile ground in closing argument before a jury,
    they have no chance of survival in the arid climate that is
    appellate    sufficiency-of-the-evidence   review.     As   we   have
    explained, credibility determinations are for the jury, not this
    court, to make, see 
    Gonsalves, 859 F.3d at 111
    , and our review
    must "resolve all credibility disputes in favor of the verdict,"
    United States v. Gaw, 
    817 F.3d 1
    , 4 (1st Cir. 2016).    Corbett made
    these credibility arguments to the jury, but the jury found him
    guilty nonetheless.     See 
    Gonsalves, 859 F.3d at 111
    (emphasizing
    this   point    while   rejecting   "hopeless"   witness-credibility
    argument). We cannot say that it was unreasonable or insupportable
    to credit the testimony of Gerrish and Gillis.    See 
    Serunjogi, 767 F.3d at 140
    .
    In a last-ditch effort to stem the tide, Corbett stresses
    that he was never found in possession of any drugs and never
    expressed the intent to sell drugs in the recorded conversation
    with Gillis.    But the government was not required to produce such
    smoking-gun evidence to secure Corbett's conviction.        See Paz-
    
    Alvarez, 799 F.3d at 25
    ("There are many ways to show that a
    defendant intended to join and advance a conspiracy, even where
    - 17 -
    the defendant never actually handled the drugs.").                 As explained
    above, the testimony of Gerrish and Gillis amply supported the
    guilty verdict.         Therefore, Corbett's sufficiency challenge must
    fail.
    B.    Court's Response to Second Juror Note
    Corbett next argues that the district court erred in its
    response     to    the    jurors'      question    about     whether   Corbett's
    expression in the recorded conversation of an intent to pick up
    the oxymorphone fell within the scope of the conspiracy.                        As
    Corbett sees things, the court's response incorrectly suggested to
    the jurors that they could consider Corbett's words or actions in
    his conversation with Gillis — who by then was a government agent
    with whom Corbett could not conspire as a matter of law — as
    evidence of the existence of the charged conspiracy.
    Recognizing that he failed to raise the issue below,
    Corbett suggests that we must review this claim under the daunting
    plain-error standard of review.           Not so fast, says the government:
    When defense counsel told the district court "I have no problem"
    with the proposed response, he affirmatively waived — rather than
    merely failed to preserve — this issue.               We start (and end) our
    analysis with the question of waiver.
    A litigant waives a claim when he or she "'intentionally
    relinquishes or abandons' a known right." United States v. Walker,
    
    538 F.3d 21
    ,   23    (1st   Cir.    2008)     (quoting   United    States   v.
    - 18 -
    Rodriguez, 
    311 F.3d 435
    , 437 (1st Cir. 2002)); see also United
    States v. Torres-Rosario, 
    658 F.3d 110
    , 115-16 (1st Cir. 2011).
    The   distinction   between    waiver   and   forfeiture   is   critical:
    Although a forfeited claim will be reviewed for plain error, "a
    waived issue ordinarily cannot be resurrected on appeal."        
    Walker, 538 F.3d at 23
    (quoting 
    Rodriguez, 311 F.3d at 437
    ).
    In this case, we agree with the government that Corbett
    waived any challenge to the district court's response to the second
    juror note.   Before the district court responded to the note, the
    court twice told the parties that it was not at all "wedded" to
    the language proposed.        Despite this clear invitation from the
    district court to propose alternative responses, defense counsel,
    when given the opportunity to voice Corbett's position, stated, "I
    think it restates the instruction already given, so I have no
    problem."   (Emphasis added.)
    We have explained that, "when the 'subject matter [is]
    unmistakably on the table, and the defense's silence is reasonably
    understood only as signifying agreement that there was nothing
    objectionable,' the issue is waived on appeal."       United States v.
    Soto, 
    799 F.3d 68
    , 96 (1st Cir. 2015) (quoting United States v.
    Christi, 
    682 F.3d 138
    , 142 (1st Cir. 2012)).        Here, the district
    court unmistakably placed the issue of how to respond to the second
    juror note on the table, and Corbett's counsel was not merely
    silent, but affirmatively stated that he had "no problem" with the
    - 19 -
    court's proposed response.        This amounts to waiver.          See 
    id. (holding that
    challenge to district court's instruction was waived
    where "the district court informed [defendants] exactly how it was
    planning to instruct the jury . . . and sought their feedback,
    twice asking if they were okay with those specific instructions"
    and counsel for one defendant "affirmatively stated there was no
    objection" while counsel for other defendants "remained silent";
    "[g]iven the judge's invitation to speak up with any disagreement,
    these reactions can only be interpreted as signifying approval
    with the instructions as previewed"); United States v. Hansen, 
    434 F.3d 92
    , 101 (1st Cir. 2006) (holding that challenge to district
    court's failure to give multiple-conspiracy instruction was waived
    where defense counsel "not only failed to object to the court's
    omission of his proposed multiple conspiracy instruction, but also
    affirmatively stated 'I am content' after the district court
    instructed the jury"); 
    id. at 105-06
    (holding that challenge to
    district court's handling of note from juror about privacy concerns
    was   waived   because,   when   district   court   proposed   a   curative
    instruction, "defense counsel responded, 'Something along those
    lines, Judge, fine'").14     So we say no more about this issue.
    14We recognize that we can, "as a matter solely of [our]
    discretion," forgive waiver in "the rare case." United States v.
    Walker, 
    665 F.3d 212
    , 227 (1st Cir. 2011); see also 
    Torres-Rosario, 658 F.3d at 116
    ("[C]ourts may excuse waivers and disregard
    stipulations where justice so requires."). Corbett has made no
    - 20 -
    C.    Enhancement for the Use of a Minor
    Corbett's   final   contention   on   appeal   is   that   the
    district court erred in imposing a guideline enhancement under
    U.S.S.G. § 3B1.4 for Corbett's use or attempted use of a minor.
    Convinced that Gillis's foray into the world of drug dealing both
    predated her friendship with Corbett and continued after Corbett
    was arrested, he insists that Gillis was "predisposed to commit
    the offense and was not an 'unwary innocent.'"
    The government must prove sentencing enhancements by a
    preponderance of the evidence. 
    Walker, 665 F.3d at 232
    . We review
    the district court's interpretation of the meaning and scope of a
    sentencing guideline de novo, while the court's factfinding is
    reviewed for clear error, with "due deference to the court's
    application of the guidelines to the facts."        United States v.
    Vega-Rivera, No. 15-2467, 
    2017 WL 3276789
    , at *3 (1st Cir. Aug. 2,
    2017); see also 
    Walker, 665 F.3d at 232
    .
    The guidelines call for a two-level increase in the
    offense level "[i]f the defendant used or attempted to use a person
    less than eighteen years of age to commit the offense or assist in
    avoiding detection of, or apprehension for, the offense." U.S.S.G.
    § 3B1.4 (2015).   The commentary for this enhancement provides that
    "'[u]sed or attempted to use' includes directing, commanding,
    argument that this is such a case, and we see no reason to excuse
    his waiver.
    - 21 -
    encouraging,       intimidating,     counseling,    training,   procuring,
    recruiting, or soliciting."         
    Id. cmt. n.1.
    The    district     court    appropriately     applied   this
    enhancement in this case.           Before the conspiracy even began,
    Corbett gave Gillis, who was then about thirteen years old, some
    money and asked her to obtain some marijuana for him.            After she
    did as instructed, Corbett told Gillis that she could keep the
    marijuana that he had paid for.              On another occasion, Corbett
    provided alcohol to the underage Gillis.              The district court
    supportably found that each of these instances were examples of
    Corbett's "long process of grooming" Gillis "to become a dealer
    for him."    In other words, the district court found that Corbett's
    conduct on these occasions — which began when Gillis was a young
    girl — were attempts to encourage, recruit, or solicit her.               See
    
    id. cmt. n.1;
    see also United States v. Hardy, 
    393 F. App'x 205
    ,
    207   (5th   Cir.    2010)   (per   curiam)    (affirming   application    of
    enhancement where defendant "cultivated a relationship with 16-
    year-old J.M., providing her with free methamphetamine"; minor
    later brought one of her friends to defendant's home to purchase
    methamphetamine; friend "eventually became a user and distributor
    of [defendant]'s methamphetamine").
    In addition to grooming Gillis, the evidence shows that
    Corbett used Gillis as a seller in this pill-trafficking conspiracy
    when she was a minor.        Gillis, who was eighteen years old when she
    - 22 -
    was arrested, testified that Corbett delivered large quantities of
    oxycodone pills to her for approximately two years prior to her
    arrest.    See United States v. Acosta, 
    534 F.3d 574
    , 588 (7th Cir.
    2008)     ("Distributing   drugs   directly     to   minors   for    further
    distribution qualifies as the type of personal use of a minor
    warranting application of the use-of-a-minor enhancement under
    § 3B1.4."); cf. United States v. Mott, 
    26 F. App'x 8
    , 9-10 (1st
    Cir. 2001) (per curiam) (affirming application of enhancement
    where defendant in conspiracy case allowed minor to sell drugs out
    of defendant's apartment; "[defendant] was aware that [minor] was
    selling drugs from the apartment and agreed to it").                Moreover,
    notwithstanding Corbett's assertion to the contrary, this is a
    case where the defendant encouraged the minor's drug activity:
    Corbett encouraged Gillis to sell pills by fronting them to her
    throughout the two-year conspiracy with the understanding that she
    would pay him for the pills once they were sold.          See United States
    v. Garcia, 
    497 F.3d 964
    , 971 (9th Cir. 2007) (affirming district
    court's application of enhancement where defendant, among other
    things, encouraged minor by fronting her methamphetamine to sell);
    United States v. Caster, 
    24 F. App'x 864
    , 867 (10th Cir. 2001)
    (similar);    cf.   
    Ortiz-Islas, 829 F.3d at 26
      (explaining    that
    defendant's willingness to front drugs to coconspirator shows "the
    importance of sustaining a regular course of business").
    - 23 -
    Corbett argues that "[t]he guideline enhancement for
    using or attempting to use a minor who is already engaged in the
    drug business and predisposed to continue in the business[] is not
    warranted."       We are immediately skeptical of this argument.        For
    starters, we see nothing in the text of the enhancement to support
    the troubling notion that a minor could ever be deemed to be so
    predisposed to criminal conduct that an adult who then encourages
    that conduct is not subject to the enhancement.           Instead, § 3B1.4
    reaches defendants who "used or attempted to use" any "person less
    than eighteen years of age" — without regard to the minor's
    propensity to obey or disobey the criminal laws.               Additionally,
    none   of   the    cases   Corbett   cites    support   his   predisposition
    argument.     Cf. United States v. Rose, 
    496 F.3d 209
    , 214 (2d Cir.
    2007) (rejecting argument that "§ 3B1.4 applies only if the minor
    is vulnerable, child-like in appearance, or predisposed against
    crime" and explaining that "[t]he fact that the minor was a large,
    seventeen-and-a-half year old drug dealer who participated eagerly
    in the [armed-robbery and kidnapping] crimes does not make § 3B1.4
    inapplicable").       Finally, in addition to the lack of support in
    the enhancement's text or in the case law, Corbett's predisposition
    argument also seems inconsistent with the purpose behind the
    enhancement:       to protect minors.     See United States v. McClain,
    
    252 F.3d 1279
    , 1286 (11th Cir. 2001) ("The unambiguous legislative
    design of section 3B1.4 is to protect minors as a class . . . .").
    - 24 -
    Reserving     that    protection      only     for     law-abiding     minors   and
    withholding it from the minors who need it most would seem to
    frustrate that clear purpose.
    But we need not definitively decide whether a minor's
    predisposition towards crime can ever foreclose application of the
    enhancement        because      the    component        parts     of      Corbett's
    predisposition       argument    in    this     case     are    either    factually
    unsupported or undeveloped.           As we understand it, Corbett's effort
    to paint Gillis as predisposed to deal drugs is based on two
    assertions.    First, Corbett asserts that Gillis "was selling drugs
    before any relationship with the defendant" got underway.                   Second,
    Corbett notes that "Gillis also continued her drug use and drug
    sales" after Corbett was out of the picture.                   Each assertion is
    fatally flawed in the circumstances of this case.
    The first assertion is factually infirm:                   Corbett does
    not point us to any evidence in this record to support his claim
    that Gillis was selling drugs before she met him.                 Perhaps Corbett
    intends to refer to the time when, at Corbett's direction, Gillis
    acquired marijuana for him with money he had given her.                         But
    Gillis's acquisition of marijuana from some unknown source is not
    evidence that Gillis was selling drugs before she met Corbett.
    Similarly, Corbett references the time when "Gillis and . . .
    Gerrish,    with     the   assistance     of    Gerrish's       father,    provided
    oxycodone to [Corbett]."         But the evidence shows only that Gillis
    - 25 -
    reached out to Gerrish to obtain the pills, that Gerrish did so,
    and that it was Gerrish, and not Gillis, who sold them to Corbett
    for a profit.      Thus, this evidence similarly does not support
    Corbett's   argument      that   Gillis   was     selling   drugs   before      her
    relationship     with     him    began.        Indeed,   the   district    court
    supportably found that these prior exchanges between Corbett and
    Gillis were evidence of Corbett recruiting and grooming Gillis to
    be part of his oxycodone-peddling plan.
    The second assertion — that Gillis continued to use and
    sell drugs — suffers a flaw of Corbett's own making:                 He hasn't
    pointed us to any authority that suggests that a minor's later
    conduct that is unrelated to the charged offense is relevant to
    the inquiry of whether the enhancement is appropriate.15                And it's
    not apparent to us from the plain text of the enhancement that
    such conduct matters one iota; the enhancement, after all, focuses
    on whether the defendant used or attempted to use a minor "to
    commit    the   offense    or    assist   in    avoiding    detection     of,    or
    15The only case Corbett cites is a Supreme Court case that
    discusses predisposition in the context of the defense of
    entrapment. See United States v. Russell, 
    411 U.S. 423
    , 428-36
    (1973). But he makes no effort to explain why the principles of
    this entrapment case — which was decided more than twenty years
    before the enhancement became effective, see U.S.S.G. § 3B1.4,
    cmt. hist. n. (indicating that enhancement first became effective
    in 1995) — should have any bearing on the issue before us, and
    "[d]eveloping a sustained argument out of . . . legal precedents
    is the job of the appellant, not the reviewing court, as we have
    previously warned."   Town of Norwood v. Fed. Energy Regulatory
    Comm'n, 
    202 F.3d 392
    , 405 (1st Cir. 2000).
    - 26 -
    apprehension for, the offense."    U.S.S.G. § 3B1.4 (2015) (emphases
    added).   In any event, given Corbett's failure to meaningfully
    develop this argument or support it with any authority, we need
    not definitively decide this point.      See United States v. Zannino,
    
    895 F.2d 1
    , 17 (1st Cir. 1990) ("[I]ssues adverted to in a
    perfunctory manner, unaccompanied by some effort at developed
    argumentation, are deemed waived.").
    Undeterred, Corbett takes another tack at avoiding the
    enhancement:     Emphasizing that Gillis sold the pills "on her own
    at a profit," Corbett argues that Corbett and Gillis were, at best,
    partners in this pill-peddling enterprise.      And, citing a pair of
    out-of-circuit cases, he insists that the enhancement requires
    "something more than a 'partner' type relationship" like what we
    have here.     (Citing United States v. Parker, 
    241 F.3d 1114
    (9th
    Cir. 2001); United States v. Butler, 
    207 F.3d 839
    (6th Cir. 2000).)
    We are unpersuaded.
    Unlike Parker and Butler, this is not a case where the
    minor was an equal partner of the defendant.     See 
    Parker, 241 F.3d at 1120-21
    (finding enhancement inapplicable where there was no
    evidence "that the defendant acted affirmatively to involve the
    minor in the [bank] robbery, beyond merely acting as his partner");
    
    Butler, 207 F.3d at 849
    & n.3 (finding enhancement inapplicable
    where "[t]he facts, at best, show only that [twenty-year-old
    defendant]     and   [seventeen-year-old    minor]   possessed   equal
    - 27 -
    authority in their commission of the [bank robbery]").16              Corbett,
    as Gillis testified, was her sole supplier of oxycodone pills.
    See 
    Acosta, 534 F.3d at 588
    .           Gillis had no say in the price that
    she paid for the pills; Corbett set the price at $22 per pill.
    Additionally,       he     fronted   her   pills   on   multiple   occasions,
    encouraging her to accept pills she "could not pay for" with the
    understanding that she would "pay for [them] the next time."               In
    short,    the     record    belies    Corbett's    characterization   of   his
    relationship with Gillis as an equal partnership.
    We therefore reject Corbett's challenge to the district
    court's application of the use-of-a-minor enhancement.
    CONCLUSION
    For these reasons, we affirm Corbett's conviction and
    sentence.
    16  We note that there's a circuit split on whether the
    enhancement must be based on a defendant's own affirmative actions
    or whether it can be applied based on a coconspirator's reasonably
    foreseeable use of a minor, see United States v. Acosta, 
    474 F.3d 999
    , 1002 (7th Cir. 2007) (collecting cases), and that this court
    has already weighed in on this debate, see United States v.

    248 F.3d 11
    , 27-28 (1st Cir. 2001) (holding that, in
    conspiracy case, defendant's "sentence could be enhanced based on
    his co-conspirator's reasonably foreseeable use of juveniles to
    further the [organization]'s activities"). We need not concern
    ourselves with this nuance, however, because the question of the
    enhancement's applicability on these facts concerns only Corbett's
    actions.
