Freaking paranoid! I used to have one living in the house behind mine. Aluminum foil on all the windows, some Bible-screamer at level 10 on his stereo. He rented there for about six months, but screwed up when he poisoned his next door neighbor's dog and threatened to kill the neighbor's wife.
Rickey-tickey-tickey...off to the funny hospital he went.
Yeah, most neighbors like it better when you poison the wife and just threaten the dog.
