Ah. I'm awfully sorry about your mother. It doesn't make up for it, not even a little, but at least you weren't around people who hated you for what you were as a child, or were jealous of it.
Your school sounds very different to mine. I think - sometimes you can fight, but sometimes you have to know when it'd just be reckless. You needn't tell me any more about it. But I don't think any less of you for it, whatever you ran away from.
