Commuting may vie with showering as the day's most perfunctory task.
But regular transit riders recognize there's at least some bit of craft to subway travel. If you know where the exits are at your destination, you can place yourself in a good spot on the arrival platform. Positioning yourself within the car, deciding whether or not to hop on the express, figuring out where to direct your glance so as not to offend someone — all these elements of the metro ride require some finesse as well.
