Nice Neighbor

What do you do if your neighbor finally gets fed up with the rumble of bass coming from across the wall late at night, gets her shoes and puts a coat on over her pajamas, walks around the block to the other side, knocks on your door, and asks you to please turn it down?

You leave a note outside her gate the next day (that she doesn't discover until a day or 2 later) that says:

Isn't that a nice way to keep peace in the neighborhood?

(PS. I added an explaination of how I make hashbrowns in the comments of my last post... for those who wondered)
