Luke 2:44
"but supposed Him to be in the caravan, and went a day's journey; and they [began] looking for Him among their relatives and acquaintances."
Does Jesus' behavior in the temple as a youth indicate He was delusional?
Children wandering away from parents in public places is so common as to be a stereotype, and we would hardly be surprised if parents express concern. At the age Jesus is portrayed, young boys were expected to show themselves able and willing to cut the apron strings, so to speak.
