When someone starts hiding the formerly communal toilet paper, that’s typically the beginning of the end.
Exhibit a) From Liz in Brooklyn, New York: “My old roommate was a huge pain for a lot of reasons, but what really did it for me was when she would finish the roll of toilet paper and then hide the new roll in her room so only she could use it.” Before moving out, Liz left her roomie with this parting gift.
Exhibit b) From BK in Kansas City, Missouri: “My roommate wanted us to buy separate toilet paper because he thought I used a lot, which seemed kind of ridiculous to me. Then, when he ran out of toilet paper he would use mine. I took my toilet paper out of the bathroom so he couldn’t use it anymore. Then he wrote me a passive aggressive note saying I was passive-aggressive.”
Exhibit c) From LJ at Mississipi State University: “I have no idea why my roommate felt the need to hide the toilet paper — it wasn’t like I was using it *excessively* or anything. A few days after this happened, we had to have a meeting mediated by the Residence Director, because they were pretty sure we were going to kill each other.”
