history: End of semester one of my roommates left without cleaning out his share of the dorm room. Housing department fined me and the other two roommates 100$ each for his laziness.
current: I had a roommate in my dorm who didn't clean up his dorm room at the end of the semester and the school fined me and the other two roommates $100. I was furious at that guy.
next: Did you try to get the money from him? He sounds like a pretty bad person.
