history: One time I let this guy crash on my couch. He seemed like a nice guy, but he took advantage of me. I found out he was eating all my food and stealing money from my room. You ever have a situation where you help someone out and just end up regretting it? yes_comma_ that is always a hard situation.  
current: Yea, I once let this guy crash on my couch rent free for 3 months, and the entire time he was taking money out my room and eating my snacks without saying anything. I knew things were missing, but he'd always deny it.
next: oh man that is horrible!  I am so sorry
