A woman, worried about crime, started to carry a hand-gun. Five months 
after she'd begun carrying her gun she came out to her car in a dark 
parking lot and found it occupied by four men. She ordered them out. They 
refused to move; she pulled her gun. Instantly four doors popped open and 
her car's occupants fled into the night. Then, as she started to load her 
groceries into the car, she noticed her car (same make and model) parked 
three spots away.
