I first thought my Nu2 son is shy. But actually not. He could talk to any person no matter what his or her age is if he fell interested. I was supprised by him to talk to a 78 year old man with a lot of money ( he late told me by indicating his house ). For me and my Nu1 son (20 year old), we really didn't understand what they talked or why they laugh. Maybe this is what we call communicating? He also talkes to salemen too in supermarket if he notices some interesting things they share. In school, if he sees teacher, he will stop whatever his doing and listen intensively to his teacher until his teacher dismisses him. The people don't know him will say he is shy. now I know he just need to find some thing that they both can talk to.
