Remember when I almost hit you with my car? When was that?

Ah yes.  It was yesterday.
 
Dear Now-Teenage-Boy-Down-The-Street,
Remember when we told you that you weren't allowed to bike in our driveway?  It was after you kept running into our car on your bike.  Well, I don't know if you've realized it, but we never changed our minds and said that you could.  So stop.  Otherwise, I refuse to take responsibility if my car runs over you.
