Somit in a Subway Car

Vomit in a subway car is a strange invasion of sterility. Of all places, a subway car is one where you expect germs to thrive. Yet you get used to the idea of the shiny chrome rails and plastic seats have a generalized dirtiness that has nothing to do with grime. When you see a giant puddle of pink puke trickling down the car as the train accerates, that false sterility is destroyed, and a new plane of dirtiness is established. I wonder how the fellow who deposited it feels about it, as he now spits flecks of vomit between his legs as the stain slides past him on the floor.
