14 year old step son (very sweet polite boy) so compliant at home and at school. Does all homework (eg gives homework updates to his dad, such as when he’ll do it), never argues, never shouts, will never do anything that may be ‘wrong’, never gets into trouble at school, goes to bed etc when told. Even if he wants to get something from a cupboard (for example) teen will stand there quietly till the person (who is in the way maybe) has moved and teen will not say a word. The only thing is that he is very anxious about time keeping and travel plans especially if they change. Normal behaviour for a teen (the compliant part) or should we be worried?
