2) Have you ever had a guest do anything upsetting while staying in your apartment/house when you weren't there?
My roommates and I each have our own cupboard of food, and the girl still managed to go into my cupboard and eat all of my rice (it was special rice, too! It was a Christmas present D:) among using other things. She also rearranged our furniture. After finding all of this stuff out, I was annoyed, but now that I've found my blackened kettle I'm kinda pissed.
