So for ds 12th birthday we are planning to take him to a local dry ski slope for a tobogganing session. I have asked he who he would like to invite along and he has told me "to be honest no one". I know he is being picked on by some of the "cool" kids at school but he does have friends, I don't understand why he doesn't want to ask them along?!!! Should I be worried or is this just him being hormonal?!!! Apparently the world hates him and his life is awful so is this just another side effect of puberty?
