oh yeah…forgot to post this earlier. to get to the train station by my dorm from Chinatown, the train has to pass through a tunnel that’s built into the building. there are windows all throughout the tunnel and people who work there have desks right by them. well, as we were passing through the building, i looked out the train window and there was a man who had gotten up from his desk, gone right next to the window and was waving frantically to the train as we passed.
