This seems to be the mantra in my apartment. You can't turn your back without your blankets being spirited off and hidden in some dark closet, or having your dirty socks "hung up by the chimney with care." I was on the phone once, talking to my family in Minnesota, and suddenly found the entire contents of my purse adorning our Christmas tree. It's a good thing I didn't drive to the store that night---my wallet was strung up!
You also have to beware of flying objects. Rubber bands, footballs, soccer balls---they are all fair game. My best advice is to duck and cover. If you do get involved, expect a few bruises.
At least life is never dull at my house.
