My landlady at my old apt. lived below me. She used to sneak into my apartment when I wasn't there and take things. Then, she would return them in odd places around the apt. When I confronted her about it, she denied. But that night (while I was away doing laundry) she snuck in and returned a few of the items...she put them on the kitchen floor. As if they'd always been sitting in the middle of the floor!!!!!! Even creepier, a lot of the items were random, but she'd had to go through my drawers and private things to get them.
I'm so glad I don't live there anymore. *sigh* FREAK!
