quirk (kwûrk) n.
A peculiarity of behavior; an idiosyncrasy

My way of dealing with a quirky person is to try to ignore the quirks. The problem with this method is, sometimes it's hard to separate quirkiness from spite. Sometimes, I feel like this person is spiteful in her behaviors toward me. Well, the behaviors aren’t toward me, necessarily, but around me. That’s the other problem. How do I know she’s being spiteful and not just being her quirky self? So, I start going around in circles in my head trying to figure out if she is trying to piss me off on purpose or if I’ve pissed her off somehow without knowing it. It is emotionally exhausting.
