One night a woman went out for drinks with her friends. She left the bar fairly late at night and started driving home on the deserted highway. She noticed a pair of headlights in her rear-view mirror, approaching at a pace just slightly quicker than hers. As the car pulled up behind her she glanced and saw the turn signal on—the car was going to pass—when suddenly it swerved back behind her, pulled up dangerously close to her tailgate, and flashed its lights.
Now she was getting nervous. The lights dimmed for a moment and then the brights came back on and the car behind her surged forward. The frightened woman struggled to keep her eyes on the road. Finally, she turned onto the exit. The car continued to follow, flashing its brights periodically.
Through every stoplight and turn, the car followed her until she pulled into her driveway. She figured her only hope was to make a mad dash into the house and call the police. As she jumped out of the car, so did the driver of the car behind her—and he screamed, "Lock the door and call the police! Call 911!"
When the police arrived the horrible truth was finally revealed to the woman. The man in the car had been trying to save her. As he pulled up behind her and his headlights illuminated her car, he saw the silhouette of a man with a butcher knife rising up from the back seat.
