I had a neighbor once, he would go out on a friday night and leave his
stereo blast till 2-3am as his security system, he had 5 surrounding
renters and never knew who was pulling his main fuse in the basement, it
was fun. He is a jerk dont talk to him, let the police and lanlord a
nasty note or no power do it for you. A couple nights of the power going
out will do it. It will take him an hour to figure it out then he will
know someone is ****ed, but not who. Just dont get caught the second
time he will run to the mains room.
