I briefly had a roommate when I was in prep school. She cried all day and night for 3 weeks because she was homesick. It made getting sleep really difficult and started really bothering me (along with a bunch of other annoying BS, like taking my clothes/makeup/etc without asking). Initially I got a new roommate and she got her own room until she said she was too lonely and wanted to switch back. I wasn't having it, so V and V became roommates and I got my own room. Stayed that way until I left for Europe.
In college I lived in Graduate Student housing. They were little one bedroom houses and came fully furnished. I loved living there

My college friends came over to my place to study or to escape their roommates.
