Oooohhhh trust me, it makes perfect sense. You pretty much described most, if not all, of the troll girls right there.

Girls are enigmatic creatures. They take a lot more effort to understand; and even when you think you do, chances are you probably still don't fully get what's going through their heads. And you probably never will. But I like to think I am getting better at recognizing the differences between "mostly harmless" enigma and "dangerously insane" enigma, if nothing else.
