Cindy B,
Sounds like you made some GREAT headway at the school today!!
I too would take these issues very seriously. I was a very bright kid... Not disruptive, but very smart. ( I did sometimes take advance placement classes ahead of my grade....) And, we WERE in the poorhouse! Anyhow, I know how that is!!! I can see how you your sons intelligence and fast-thinking translates in what could be seen as 'overbearing'. And I know how this can translate into social problems. If it is anything like me, your son 'knows what he knows!!' He is thinking so far ahead of the other kids, not just in academics, but in EVERY way. I never dumbed-myself-down on academic tests, but did feel like I had to dumb-myself-down to relate socially to the other kids! I really felt for you and your son when I read how he said he didn't want to be smart forever!!
the reason that I spent a lot of time alone was that it seemed like thankless work to try engage in the nonsense tit-for-tat social behavior (including the silly "stupid lives in the poorhouse" name calling that the other kids commonly engage in.
If I am on the correct assumptions here, ( Please forgive me if I am not!! ) it is not just "read a book if he finishes his assignment", or "Challenge his mind". You are doing really good to take a pro-active view of the situation! Improving your sons social situation will probably be the biggest most wonderful thing that could happen! If your son manages to make even one good friend at school, then he will not be 'alone' and that will make all the difference! ( I notice how you said that your child was not really 'alone' as much he felt that he is 'alone'. Is that maybe due to the lack of having one good friend to connect with? I do remember a 20/20 special about children-bullying-etc... in which the specialist said that if your child is that unhappy at school, and doesn't seem to have one friend, then that is the time to step in.... So, good work so far!
OHhhh I know how it hurts to see your child hurt!!! I really feel for you!!! More hugs!!! Remember- this too shall pass!
Hope this helps... feel free to PM me....
