I'd leave a note just because thats how I am.
About 5 years ago, I was watching some ******* trying to back up over a snow mound that I had in front of the car. Now keep in mind, the snow mound was in a "fire zone" in front of the fire hydrant. No, I didn't block the hydrant if anyone asks. Well here I am watching this doing this.. He gets a head start, right up over the mound, and into my old IROC. Taking the front paint off the bumper. I walked out, tapped on his window, said thanks, then kicked out his tail lights.
People say I need anger management classes...
lol.
