history: I had people stay at my house while I was  gone over the weekend, so they wouldn't have to pay for a hotel. When I came back, they had left a mess and didn't really put in much effort to put things back where they found them. They were supposed to be good friends, too.

Did you confront them about it? I am sorry you have to deal with that.
current: Not really. I hate confrontation. And nothing really of cost was lost. I'll just lose time in cleaning up after them. It definitely is a learning experience when it comes to trust... Doubt I'll be an AirBnB host any time soon!
next: That's too bad. Lesson learned, I guess.
