here's a question

okay, so imagine you're standing a subway platform in new york city where the trains run every 5-10 minutes depending on what time of day you're there. they usually run without fail and a train always comes. so why do you lean over the edge of the platform to look down the rail avidly? i don't quite get it... i catch myself doing it too. i mean, what advantage do you have seeing the train first on a crowded platform? why do you need to see the train coming down the tunnel? does it prove it's coming? but they always come. i don't know, i was wondering this on the way home. i think hearing it and seeing it when it's down the platform is enough... i don't get why people lean forward to look when it's 99.99% guaranteed to arrive.

it's weird.
