Nancy, I have not responded straight away about your son, as when I first read your reply I got tears in my eyes. So I thought I should sleep on it. I still don't know what to say really other than we are all different and have different brains - der that is dopey - if we weren't all different the world would be a sad place. Please make sure that he is careful as if this had happened to me when I was a teenager I don't think I would have coped. Best of luck.
