Whats with his parents?

I know this guy, and he is Amazing! Nicest teenage boy you vould ever meet. He isn't crazy and rebellious, he doesn't get into trouble and yet his parents are sooooo strict with him! I don't understand it. What is the deal? I wish I could grab them and shake them! Maybe they need some sort of phsycological reasurance that their son isn't going to go out and rob a bank and do drugs! Maybe they need to know that he has good friends! I want to tell them! However, they mostlikley wouldn't trust me since they don't know me because he doesn't talk to them about his friends. :(
They need to see that they can trust him! I trust him everyone else seems too except for them! Please don't smother your child!!!!!
