Why Such a Rush?

I laugh everytime at people who are in such a hurry to exit the subway train that they get up from their chair before the train comes to a stop - only to get thrown across the car into other patrons standing quietly on the side. Can't these impatient persons wait just a few more seconds? It's not as though they can exit before the train comes to a complete stop. The doors won't open! Lesson learned people. Lesson learned.
