i am 22 now, my parents never interfered with my social life and i think everything was fine, i was top of my class, i had friends, i never got bullied, i am a final year medical student right now. things are hard for us to get what everyone normally gets but you cant protect him for ever, he has to try do things in his way. you can keep an eye on him, he is your son i think if anything bothers him you will know it or at least feel something is wrong.
