After you move into a new place, you will sometimes get the mail intended for the previous occupant. We've lived in our house for almost seven years now, so it was a surprise to get a letter at the end of this week from the former owner, and addressed in her maiden name no less. Somebody's junk mail database is in need of an update.
If I have the time, I like to draw a small, fairly elaborate RTS message. I believe Elvis does it best: "Return to sender/address unknown/no such number/no such zone." The postal delivery lady appreciates these little cartoons, even if I only get to do this once every five years. Whoever sends us this junk mail never sends us any more. (I've deleted the mailing information to protect privacy.)
