A Note on the Door

We saw this note taped to the inside of the screen door on a house in our neighborhood. It says:

"My business is my business So your business is your business. So please do me a favor! Stay out of mine, I'll stay out of yours---or just stay away!!
Also, I am not a baby sitter & I am not a taxi & I am not a MAID!!
So use your common sense when reading this!!!"

I'd love to know the back-story of this, wouldn't you?
