Is he violent? Are you afraid of him? Does he break your things?
I am also glad, and not surprised, that he is doing well. Although we don't know the street tricks, they learn them fast and they don't seem to mind them either. If they REALLY hated the streets, they'd follow our rules so that they could live at home. None of us said they can't come back IF they follow our rules, most which are really just normal stuff for a kid over 18, like work and do chores.
