When getting onto an already over-crowded train, is it somehow more polite to turn around and push backwards into people? Is that how it's supposed to be done? Is the idea behind that to make me want to give you "your" space when there already isn't enough space for everyone currently involved?
Lemme tell ya, all it really does is make me want to remove the closest kidney with a pencil. Chances are, it's gonna be yours, since it's currently being thrust in my direction.
