Disco>sweat>disuse. I imagine a very popular disco filled with dancers and bright lights. I can see the disco ball flashing and hear the BeeGees playing. The dancers are sweating profusely. In fact, they’re sweating so much it’s beginning to flood the dance floor, run out the door and into the street. Everyone leaves in disgust. I can see the discotheque now, abandoned. There is a thick layer of dust on everything and spiderwebs on the disco ball. It’s fallen into disuse.
