My rule regards laundry rooms- this applies to those living in apartment buildings. Sometimes, people forget and let their laundry sit in the dryer, so you have to take it out in order to use the machine.Of course, you usually leave it there and they pick it up. But I remember how some of the dingbats in the building would leave their clothes there for days or even forget about it entirely.
How do you forget your clothes for days on end? I notice if even one pair of my socks is missing. .

And sometimes it was pretty swell stuff with nice labels, from some of the better stores. Anyone who is too stupid to remember to pick up their clothes after a week shouldn't be surprised if the elves make off with their stuff! I guess if you're a spoiled student whose parents pay for your rent and everything else, you can afford to leave your nice clothes in the laundry room- heck, you can always buy more! Hard cheese! Them's the rules.
