Well, I've also seen people who weren't dangerously insane before end up that way somehow - the sort of thing where they normally would have been fine, but they had some sort of...incident, I guess you'd call it.

[He twitches a little once that's out there, though, because it occurs to him that that...isn't necessarily limited to the girls, is it? Just. Give him a moment, hang on.]

But in general, I've found girls to be more difficult to relate to than boys, insane or not - in the school I was attending back home, there was at least one I knew that was strange to the point that I'm not sure how people talked to her in the first place, and many of them tend to be either entirely too open or completely closed off. It's...strange.
