When my roommate moved out last year, she left behind a ton of garbage and junk, and never came back to finish cleaning up. When I moved out of the apartment a month later, I had to do all that cleanup.
In with the various garbage was nearly every gift I'd given her over the year, be it birthday, Christmas or just silly stuff. She had received every gift graciously, and in several cases was really excited about it.
Am I more than happy to take her to court over the back rent she owes me? Hell, yes....!
