I have the worst luck ever when it comes to roommates and neighbors. My experiences with roommates were just ew. So please read this post and learn to not be that gross roommate.
First off, please don't think I'm completely anal about the smallest things whenever I have roommates. I understand some noise and mess. I'm a horribly messy person. However, my mess stays in my personal areas and I cannot leave a shared area messy. That's rude. End of story. Needless to say, most of my past roommates have one thing in common: they were complete slobs.
