history: I once took in a roommate because he had nowhere else to live. He seemed like a nice guy and we got along at first. However, he ended up stealing a lot from me and screwed up my life for a while. Hey_comma_ how's it going? Isn't it tough meeting new people these days?
current: Absolutely. It doesn't help that I'm pretty introverted.
next: Same here. It also sucks when people let you down. I once let this guy crash on my couch because he had lost his apartment, and it didn't end up good at all.
