i set a trap in my apartment long time ago as i suspected the management was waltzing in/out without telling me while i was at work.
it was a string tied low to my lamp stand and the other end to a leg of my desk.
sure enough i come home the lamp was not positioned the same way.
walked over to management the next morning, they said they had to fix something with the plumbing.
yah right. without notice?
