A bit OT, but I tend to walk around my apartment stark naked with curtains open. If someone sees me from the opposite apartment block, (6th floor) who cares. It's their problem if they are disturbed by something I do at my own home. However, nudity is not a strong taboo here, so no problems with that. And complaining to the authorities may cause them to take interest in actually why is someone watching their neighbour anf monitoring their windows..

But yeah, coupla years ago I lived for a few months in a student dorm (single person rooms) where the proprietors conducted housekeeping inspections. Sometimes they busted right in. One afternoon I was preparing to leave and, as my bladder was bad, I was putting on a brief-type diaper that no one could mistake for anything else. The pack's open on the chair and I am fastening the tabs when a knock comes from the door and I hear the master key turning in the lock.
Janitor: "Housekeeping inspection!"
Me, petrified, eyes nailed at the yet shut door with a diaper between my legs:" Ummm, ah, I haven't really kept it at pristine condition this week, cleaning up right now! Could you come back later!!?"
Janitor's voice: "uh, ok". Key pulled back, footsteps disappearing.
That was one close call.

If they ever had inspections when I was out, I am sure they saw a pack. I forgot to put it out of sight once or twice when leaving in a hurry. Didn't like that kind of intrusion...
