When someone accidentally hits a parked car, they have two options. The first option is to be a decent human being, leave a note with their information, and deal with the financial consequences of their actions. The second option is to leave a bad parking note, save face, and run like hell. If you've ever been the victim of a hit-and-run, then you may be familiar with snarky notes from your local a**holes.
And if you haven't been the victim of this automotive tragedy, just wait. It will happen to you one day, just don't let your anger morph into any road rage.
