Why horror, you ask?
That was an actually question once. Why write things that are gross, or scary, or both? Sure, there's an answer out there that's deep and meaningful about looking into ourselves at the monsters within us to accept blah blah blah. The truth is, whenever I write a scary story, it's because it's something that's been stuck in my head, and if I don't get it out, it'll keep looping around in there. And that's no fun. Once it's on paper, it's exorcised. Added bonus, if it scares someone else, or makes them cringe at least, you can say "see, I'm not fucked up, THAT is! And I'm glad it's out of my head!" Okay, say that last part to yourself. It's true...but nobody wants to hear that.
