Man, I feel for you. It's not easy to be a parent. I am lucky that both of my kids never really had any problems in that nature. They have good disciplines. I would suggest that you and your wife have a real heart to heart talk with your boy. And ask him what he is going to do to turn his life around. If he has the right answers, he will be much more committed if this comes from himself. I know you are very angry at him and he needs discipline, but I hope he does not become rebellious. Perhaps another close member of the family, such as your brother, sister or your wife's side, can have a good talk with him. Hope things turns out well for you and your wife
