I live in the village, my roommate always leaves the common area (e.g. living room, kitchen) in a mess. For example they left the dishes on the sink for a month and there are a lot of flies that come to my place. In the end, I was the one who washed all the dishes. It is really disgusting. Also, sometimes, they throw everything on the floor, sofa, etc. As I remember the last time when I was sitting on the sofa, a knife was right next to me. It is really, really dangerous.
