Did you ever have a terrible roommate? What did they do that bothered you so much?
Anyway, the guy who's name was on the lease used to play loud music, one time we were sitting listening to music he goes 'I love this song' and reached over and cranked it up so high that I flinched sideways from the noise.
Another time I couldn't sleep because he was playing his guitar badly (more like strumming the same note over and over again), wailing with the 'music' and stamping his foot on the floor in time with the music into the wee small hours. When I finally yelled at him to go to bed he said 'Listen you freaking freak'
I later found out from a former roommate that he had lost a lot of roomies due to the loud music
