Cars. I don't like them D: I'm okay with being in them, but whenever I'm in an area with a bunch of cars driving around while I'm walking, I always freak out. I don't know why, it's pretty obvious they're not gonna hit me, but there's always this sort of anxiety, I guess, when I'm near moving cars.
I also don't like being close to people I don't know. Another one of those weird things that freak me out a whole bunch for no good reason.
My final pet peeve is people who go on threads like these and post really obvious stuff (i.e. "Hypocrites, stupid people, jerkfaces, etc.) It's like, no, really? Who in the world has ever said, "Hey! This person is obnoxious/cruel/a hypocrite/a liar/a moron! This sounds like the kind of person I would want to hang out with on a regular basis!" Nobody, that's who.
