i had a roommate that refused to leave the dorm to buy toilet paper. we had an on campus dorm that was basically an apartment...our own kitchen, bathroom, shower, etc. anyways, we got assigned together but NEVER talked. Like 5 minutes total the entire school year. Not exagerrating. Anyway, we got low on toilet paper and I wanted to see if he'd going out and buy some, since he never seemed to pony up money for "communal" supplies like that. So, i bought my own but stashed it in my bedroom and kept it only for me. When the last of the TP in the bathroom ran out, I waited to see how long it would be until he broke down and needed some. one day later a roll of paper towel from the kitchen showed up in the bathroom.
Nasty. I think he finally bought some toilet paper at some point perhaps a nearly 2 weeks later. I have no idea what ever was going through that kids' head. But I sure had fun experimenting on him.
