Ha! When I worked at a factory, a couple of people were fanatics about picking up pop cans for the deposit. One time "Sally" (an older lady) picked up some pop cans that were promised to "Gerald" (older coot). He got mad and super glued her combo lock shut. They had to get the bolt cutters. Gerald got a write up.
Day after day, it reappears. Night after night my heartbeat shows the fear. Ghosts appear and fade away. Come back another day.
