Raced down the stairs toward the waiting subway car. As I landed on the bottom tread, the doors closed with the customary ping. Took the three steps so that I reached them just as the shutting action was completing. I looked to my right, down the platform, the conductor in the middle of the train, happened to be checking my direction, and as I ‘signed’ something, he slid the door open and quickly shut. I slipped into the car between those two actions. Those are the days you think all is right with the world!
