Looks like you're talking about me here.
I don't have much idea of why I sometimes get upset on some forum post or what someone has said. I guess it's that I'm not the happiest bunny around and then there comes someone and says that I'm wrong in one more thing and that makes me think that the whole way of my thinking and feeling is wrong.
Funny thing is that I don't really like the term "over sensitive" either. It's as if I'm somehow disabled or something is wrong with me. (I guess there is then if it's over-sensitive)
Anyway, this forum post didn't make me upset - you can sleep in peace which I see you're currently doing.
