DS is 8. He Has always been a bit of a loner by choice and doesn't like to just do what others do, for example he won't play a game just for the sake of it if he doesn't like it he will play by himself. He doesn't have any real friends as such. He seems to get along ok with most of the children in his class and flits about playing with whoever suits him. However this year he does have some boys at school that he wants to play with more than others but sometimes when I see them in the morning they seem unfriendly to him. I asked him about this and he doesn't feel this way or think that they are mean to him or leave him out, he thinks they are his friends. I have spoken to his teacher who has watched him at playtime and said that he generally plays with others. I have niggling doubt that these 3 boys leave leave him out but he denies this many times. I think I am projecting my own feeling of being left out and bullied when I was at school and hating it. However I don't have this worry about my other children but they are more outgoing like me and DS is an introvert. Am I AIBU to just have an awful niggling feeling about him but not know what to do.
