21st Century Horror Story (Short story)

You hurry onto the subway train, and to your relief find a vacant double seat. Though the car is packed, no one sits down beside you. A slowly spreading smell offers an explanation. You look around, scanning the passengers and walls. Where does it come from? You spring to your feet as the train stops at the next platform, and rush out to change line. On this new train, you are immediately greeted by the same smell. How? Did the smelly person follow you?
You hold your breath. Soon home.
In front of the mirror, sweat pouring down your face, you can no longer run from the truth.
The smelly one is you.
