I took this snap a while back in the Tokyo subway while waiting for a train to arrive. In Tokyo, the trains of major subway lines arrive at the platform every few minutes. Especially during the commute hours, businesspeople pour out of the train cars and new passengers stream inside to take their place. If it's during the busy hours, you would often have to be squished inside. It's always a relief to be on the way home after a long day of work, and that's the feeling I think this scene gives off.
