Granted, he's what...24 or 25 by now. But where the hell are his parents? They should be trying to get a handle on this kid and help him get his life together.
Perhaps he won't even listen to them, which is pathetic. They gave the kid a new life. Obviously they didn't parent worth a ****, but they did give him a launching platform.
This is pretty unfair to his adoptive parents, IMO.
