Mischievous

I'm rarely mischievous, but this morning I was. Tailgaters.  Ugh.  Nerve wracking.  My cure, or revenge, is to turn my windshield washers on.  The person who is toooo close really doesn't like to be sprayed with water and thus have to turn their windshield blades on.  Especially irritated are those in a nice, shiny, black fancy car...
