One of the reasons I hated being in student accommodation a couple of years ago was the amount of mess my flatmates left in the kitchen, so I can definitely sympathise.
@ honeybees; Exactly! Last trimester most of my housemates were different people because my house tends to attract exchange students. Anyway, I'd occasionally clean up other people's crap and somehow that escalated into me always cleaning up. I really didn't want things to end up like that again.
I have to constantly tell my roommate, who is also my boyfriend, to clean up after himself. What makes me mad, though, is when he doesn't so anything I ask him to do which means I have to do it or it will never get done. Unfortunately, because of this, I've become resentful of having to do everything and just don't want to live on my own anymore.
