The juvenile, aged twelve years and eleven months at the time of the events recounted below, is charged in the juvenile session of the Lawrence Division of the District Court with delinquency by reason of manslaughter. During interviews on December 18 and 20, 1989, the juvenile *805 made oral admissions and signed two statements, in which he admitted that he had set fire to a couch located on the porch of his family’s second-floor apartment on the evening of December 17, 989. The fire spread throughout the three-story wooden dwelling. A Lawrence fire fighter was severely injured while fighting the fire and died of his injuries on December 20, 1989.
The juvenile moved to suppress his admissions and statements. After an evidentiary hearing, a District Court judge, sitting in the juvenile session, allowed the motion. The Commonwealth was permitted to appeal, see Mass. R. Crim. P. 15 (a),
The facts are set forth in the opinion of the Appeals Court and need not be fully repeated here.

During the remainder of the interview, the. juvenile changed his story several times. At one point, the juvenile *807 became angry and ran out of the room. The investigating officials did not follow him. Officer Dwyer assumed the interview was over and went to another room and began interviewing other witnesses. Captain Ord also left and did not return. On her own initiative, the juvenile’s mother brought him back, and the interview resumed. The juvenile eventually initialed a statement in which he admitted to having set the fire unintentionally.
On December 20, 1989, the juvenile returned to the fire station. His mother met him there and was present while he was interviewed by State police Officers John Garvin and Paul Zipper. Officer Garvin read the juvenile and his mother Miranda warnings and the waiver provisions from a printed card. Officer Garvin informed them that the juvenile did not have to make any statement, and he inquired whether the juvenile and Mrs. Smith understood the warnings. Both responded affirmatively. Officer Garvin then asked whether the juvenile wished to waive his rights and speak with the officers. The juvenile and Mrs. Smith responded affirmatively. Both the juvenile and Mrs. Smith signed the waiver provision on the Miranda card. The officers then left the juvenile and his mother alone together for somewhere between five and fifteen minutes, instructing them to discuss the juvenile’s Miranda rights. The juvenile and his mother were not conversing when the officers reentered the room, and it is not known what, if anything, had been discussed by them during their time alone. Before reentering the room, Officer Garvin asked, “Would you like to talk to us now? I would like to get a statement from you regarding what happened with the fire.” The juvenile answered “yes,” and Mrs. Smith stated that she wanted the juvenile to tell the truth.
The ensuing interview lasted approximately four hours, with two or three breaks, initiated by the officers, each lasting between five and twenty minutes. The officers left the room during these breaks. At some point, the juvenile was offered, and declined, a soda. The juvenile’s story changed frequently during the interview. Mrs. Smith on occasion became frustrated with his responses and urged him to tell the *808 truth. At the end of the interview, the juvenile and his mother reviewed for accuracy, and initialed, each page of an inculpatory statement. When the interview was concluded, Mrs. Smith did not want the juvenile to return home with her. At her suggestion, a social worker who had previously counseled the juvenile was brought to the fire station and arranged for an accommodation for the juvenile in a juvenile home.
The judge concluded that the juvenile’s motion to suppress should be allowed because the Commonwealth had not shown that Mrs. Smith satisfied our “interested adult” rule and that an actual consultation had taken place between the juvenile and his mother prior to the interviews. As an alternative basis for allowing suppression, the judge concluded that the “totality of the circumstances” indicated that the juvenile’s statements were involuntary. In reaching the conclusion about involuntariness, the judge relied on the juvenile’s age and lack of familiarity with police practice; the height (over six feet), and bearing (including their concealed handguns) of the interviewing officers; their urgings that the juvenile tell the truth; the fact that the juvenile and his mother were furnished Miranda warnings only twice; and the additional fact that the officers did not remind the juvenile that he and his mother were free to leave.
We turn now to the principles that govern the appeal. Investigating officials permissibly may interview a juvenile suspected of a crime, and a statement that is the product of that interview, if knowing and voluntary, may be admitted at trial against the juvenile. See
Commonwealth
v.
Tavares,
The judge concluded that Mrs. Smith was not an interested adult because she had not actually engaged in “ ‘counseling’ [the juvenile] vis á vis the exercise of his privilege [against self-incrimination].” The judge also considered that Mrs. Smith was not an interested adult because she repeatedly urged her son to tell the truth; she brought him back for further interrogation when he angrily left the room during the December 18 interview; and she became upset at times over his behavior and responses. The judge also relied on facts that, at the close of the second interview, Mrs. Smith did not want her son to return home with her, and she did not attend care and protection proceedings concerning her son instituted in June, 1990.
Interested adult. In deciding whether an adult advising a juvenile during a custodial interrogation is an interested adult, the facts must be viewed from the perspective of the officials conducting the interview. Commonwealth v. Berry, supra at 37. If, at the time of the interrogation (as assessed by objective standards), it should have been reasonably apparent to the officials questioning a juvenile that the adult who was present on his or her behalf lacked capacity to appreciate the juvenile’s situation and to give advice, or was actually antagonistic toward the juvenile, a finding would be warranted that the juvenile has not been assisted by an interested adult and did not have the opportunity for consultation contemplated by our rule. Id. at 36-37.
*810
The judge did not find that Mrs. Smith lacked capacity to appreciate the situation facing her son or to give him appropriate advice. There is no objective basis in the record to support a finding that interviewing officials could have concluded that Mrs. Smith was antagonistic toward her son. She appeared concerned about her son, not angry with him, attended both interviews, and was attentive to the administration of Miranda warnings and provisions about waiving rights. The juvenile appears to have considered his relationship with his mother intact. Cf.
Commonwealth
v.
Smith,
*811
Actual consultation.
In
Commonwealth
v.
A Juvenile,
We conclude that the juvenile and his mother had the required actual opportunity to discuss his rights on both occasions on which he was questioned. On December 18, after Officer Dwyer furnished the juvenile his Miranda warnings, the officers left the juvenile and his mother alone in the room for five to fifteen minutes. 5 On December 20, after the officers read the Miranda warnings to both, mother and son were again left alone. On this occasion they were specifically *812 instructed to discuss the juvenile’s rights. It is not reasonable to infer from the fact that the two were silent when the officers reentered the room that they had not spoken to each other while they were alone. Nor do we think that Mrs. Smith’s failure to ask the officers questions about the juvenile’s rights is any indication that she failed to understand the content of the Miranda warnings which had been read to her on two occasions.
Unlike several other States, see
Hall
v.
State,
This court observed in
Commonwealth
v.
A Juvenile, supra
at 135, that “establishment of definite procedures ‘has the virtue of informing police and prosecutors with specificity as to what they may do in conducting custodial interrogation, and of informing courts under what circumstances state-
*813
merits obtained during such interrogation are not admissible,’” quoting
Fare
v.
Michael C.,
We turn to the judge’s alternate basis for suppression, namely, that, under Federal constitutional law, the totality of the circumstances indicated that the juvenile’s statements were involuntary. That conclusion, it will be recalled, rested on the juvenile’s age and inexperience with police procedure, the height and bearing of the officers, their comments, and the context of the Miranda warnings.
There was nothing to show that the juvenile was impaired, mentally or otherwise, or that investigating officials used threats, promises or subterfuge to induce him to speak. The setting for the interviews, a small office in the fire station, was not forbidding, and the questioning proceeded routinely. We decline to consider requests of the juvenile to tell the truth as coercive practice. The height of the officers is not of *814 significance (and neither is the fact that they carried concealed weapons, which, obviously, were not seen by the juvenile or Mrs. Smith). While it is appropriate to consider the juvenile’s youth and inexperience with police procedures, his age and lack of encounter with the police alone would not warrant suppression. Were it otherwise, investigators would not be able to question a thirteen year old boy whom they reasonably suspected of involvement in a serious crime. Miranda warnings were scrupulously furnished, understood, and waived. Officer Dwyer, the officer who gave the juvenile his Miranda warnings during the first interview, indicated that he had advised both the juvenile and his mother , that they were free to terminate the interview at any time. Because the interviews occurred in a custodial setting, there was no requirement that the juvenile be told that he was free to leave. Finally, we note that neither Mrs. Smith nor the juvenile testified at the hearing so that no evidence was provided by them upon which a determination of involuntariness could be based. We conclude, therefore, that the juvenile’s statements should not have been suppressed as involuntary under a totality of the circumstances analysis.
Order allowing motion to suppress reversed.
Notes
The Appeals Court opinion states that “[t]he subsidiary facts ... are contained in the judge’s findings and in the record of the proceedings before him ... [and] are largely undisputed.”
At the point of administration of Miranda warnings, after the juvenile had made statements which indicated that he had been untruthful about his role in the fire, the juvenile was in custody. He was in custody at the December 20 interview as well. The reasons for this conclusion, which was not the subject of an express finding by the judge, are set forth in the opinion of the Appeals Court with which we agree. See
The interviewing officials could not have anticipated that Mrs. Smith would not want the juvenile to come home with her, when the December 20 interview was completed. Interviewing officials will make their assessment of the relationship between parent and juvenile at the outset, and during the course of, an interview. Evidence of events occurring at the close of an interview logically cannot be used to support a finding that the officials should have known a parent could not act as an interested adult. Certainly, officials interviewing the juvenile in Mrs. Smith’s company in December, 1989, could not have taken into account care and protection proceedings initiated in June, 1990.
When the officers left the juvenile and his mother alone during the first interview, after reading the Miranda warnings to both, they did not instruct Mrs. Smith to discuss her son’s rights with him. We have never stated that investigating officials must expressly inform a juvenile and his or her parent that they should use their opportunity to confer for a discussion of the juvenile’s rights, and we do not do so now. See
Commonwealth
v.
Ward,
Investigating officials can only provide a juvenile and an adult the opportunity to confer about the juvenile’s rights. They cannot force the adult to speak with the juvenile, nor can they dictate the content of whatever discussion takes place. In addition, we cannot hold a parent or an interested adult to the standards to which we would hold lawyers in explaining a defendant’s rights and the possible consequences of waiver. Thus, we do not accept the Appeals Court’s suggestion that the Commonwealth must prove that the “consultation conveyed the vital information that [the juvenile] needed to know.”
The Appeals Court upheld suppression of the statements made during the December 18 interview on the grounds that the juvenile had not himself signed the waiver provisions of the Miranda card and because “there is no suggestion in the record or in the Commonwealth’s brief that [the juvenile], by any other act, waived his rights.”
A written notation of a juvenile’s waiver of his rights is not an essential prerequisite to a valid waiver.
