Always Find Witnesses
I noticed that a rude person next to me had parked way over the line (I work at a hospital and even a small space is a godsend). I decided to take a picture of my car which was well within the lines, and the rude person’s car which was way over the lines, including her license plate. The driver could not get into her car because mine was too close to her driver’s door.
So, in a rage, she climbed into the passenger side, opened her door into mine three times to intentionally dent it, and drove away. Luckily, with the photo I took of the license plate and two witnesses, I successfully reported it to the police.
