I have edited this picture so you can more easily see the difference in the white mounting area of the platform:
it was a fine early autumn evening, when i thought to myself, i wonder if there is a way to tell where the doors on the cars of the train will stop along the platform? i wonder if it is more worn, if it is dirtier. then i thought, perhaps it doesn't stop at the exact same spot every time. and just as i began to doubt, i spotted that the white is dirtier all along the platform where it is the most used. Isn't that great??! isn't that so cool?! so, if you come here, don't be one of those people who pick a door, and walk with it while the train is still moving, and you keep following it looking like an idiot. instead, if the metro is not really busy, you can stand directly in the middle of one of the splotches and wait. if it is rush hour, stand just next to the splotch, because no doubt people will need to exit before you get on to the train.
yeah, just ask me if you need anymore tidbits about looking like you totally know what's going on in the metro.
