Monkeys...I am so sorry your son (and you) is going through this. Our society is so unfair when it comes to anyone who doesn't fit the stereotypical mould! Unfortunately, we cannot force other kids to be friends with someone (although of course we can expect fair treatment)...I see the problem. It is impossible for you to monitor everything and to step in every time...and it may not help in the end since when you are not there, they will do it anyway (not saying you should sit back and do nothing). I wish I had some good advice, but I don't. It sounds like you are doing everything right...trying to teach him to be strong and not let it get to him...but he is a kid and he is human and of course it is going to hurt his feelings. I am just sending lots of empathy and hoping that he finds a way to stop the bullying
