I'll admit, I returned to my car in the parking lot one night after dinner to find a small ding in the driver's side door of my car. There was also some blue paint left with the ding. Low and behold, the car parked directly next to me had the same blue paint and their passenger door was lined up perfectly to the ding.
I was livid. It was a small ding, but I simply hate people who are so self consumed that they care nothing for the property of other people. Without much thought, I cocked back and kicked the side of their door so hard it left a dent about a foot in diameter. I took a deep breath, got in my car and drove away.
The instant vengeance felt so wonderful, warm and fulfilling.
