Kvmum has raised very good points there.

DS(16) is one of those kids that has very little in common with his age peers and I do think it's not just his giftedness but his introversion that plays a part in how he interacts with others. I have been fortunate as I have been the one who has worried endlessly over this but not the school. In their opinion he is well liked and respected and that's what matters, not what he does or doesn't do at lunch time. So what does he do with his free time at school now? Hang out in the maths/science staffroom of course.LOL.
