Last week, I was coming home from Brooklyn on the N train. It's a fairly long ride, Crown Heights to Astoria, and when I transferred at Atlantic-Pacific, the train was already full. It wasn't jam-packed, but there were no seats left.
I knew that the train would empty out (and fill back up) at Times Square, but I didn't want to stand for that long if I didn't have to. I took a look around and positioned myself in front of some tired looking older Asian folks. Then I waited. The next stop was Canal Street, which, as it happens, is the entrance to Chinatown. The Asian folks got up and I got my seat.
