We Have A Winner!!! 02/20/10
Dearest Neighbor,Winner: Pamela
You know you're loud. You know you're annoying. And I know what I know. What is that you ask? I have friends in all the "right" places. Friends who will help me "hide the body". Don't even think of using this note as blackmail, it's untraceable.
Do. The. Right. Thing.
Your Worst Possible Nightmare
Reason: Nothing says neighborly like a nice threat!
P.S. Have a great day!
