Sounds as if you have a good handle on this parenting thing, if he is kind and caring you know you are doing the right things , let him bring friends home and visit them at their house.Too much Computer and TV and Game Boy stuff seems to prevent children having the great experience of Sports and Games and other outside activities., so it is good to allow it but limit the use each day.To some extent you can only guide by your actions and hope he makes the right decisions, plenty of talk is good and focusing on his positive side which is what you are doing, congrats you are going int he right direction.
