Anybody can pass me any time they want; what I said was I wouldn't try to pass anybody else. And ten seconds can make the difference when running for a train? Big deal. So can the train running ten seconds slower or faster. So can the number of people going through the turnstyle ahead of you. So can stopping to sneeze a couple of times on the way to the station or holding the door for an old timer carrying a shopping bag. "Sorry, lady, gotta beat the clock." Thump. Seriously, I think people these days look for things to get uptight about. Slow down. Mellow out. Repent, Harlequin.
Ok, but I can't really influence any of that and more importantly subjectively I don't know that holding that door was what caused me to miss that train. On the other hand if I'm on top of the escalator and I hear the train pulling into the station and there's some guy blocking my path because he's taking the train in the other direction and doesn't care I know exactly why I missed it.
