Driving home one night, my cousin's roommate stopped at a gas station. Shortly after leaving, the car that had followed her back on the road pulled up close and flashed it's brights. When she glanced in the rear view mirror, car backed off. The driver did this repeatedly following her all the way home, each time flashing the brights and then backing off when she looked in the mirror. She was able to make it home. She pulled in to the garage which was attached to the house and closed the door before the other car pulled into the driveway. Inside she heard someone pounding on her front door. "Ma'am there's someone in your garage!" A man called. It turned out that when my cousin's roommate stopped for gas a serial killer had crawled into the back seat of she car. The other driver had seen it but she left before he could do anything. So he followed her home pulling up close and flashing his brights every time he saw the intruder's head start to show in the back causing him to duck back down. Done all in PSP in 2 evenings
