Some of my housemates disrespect our shared spaces.
It's frustrating. One of my housemates actually talked to me about this, and asked me to approach another housemate and talk some sense into them. Very frustrating, indeed.
Something that does upset me particularly is the way they hog the clotheslines. There are three clotheslines for 4 people, but one of us usually dries their stuff outside, on a 4th clothesline. Still, somehow, every single one of them is constantly filled with rags and other stuff. Not even clothes! It drives me crazy... I did find that today, at least, there was one empty, save for a rag, which I moved, so I could actually do my laundry.
Whatever.
