What roomate quirks do your maxis premades have?

Gotta love those roommates :) There's always something that surprises me, or a quirk I miss. One term there were nobody bringing free food and it actually took me a simday to realize I had to provide my sim with food somehow :)

My favorite might be the Repair stuff trait, it's very useful and they fix stuff rather quickly. Some of my students with a locked door, might move their stereo or computer out to the common room just for getting it fixed.
