I suppose this is a New York City topic, but it applies everywhere.
Getting back in forth in the Big Apple (why is it called that, anyway?) requires trips on the subway. Crowds of people press into cars, compete for seats, and steady themselves on poles and bars. The average rider doesn't see the people as any more than units, together with himself on the ride.
But look again. Each person is a whole universe. They have an entire life filled with family and friends. They have a job. They have problems; they have joys. They each a complex being full of thoughts, feelings, and aspirations. It's amazing, sometimes, that the small space of human body can hold so much.
But beyond that...there's a crowd. How many people on this subway car? How many on the train? How many in the country and how many in the world? Each one is holding a whole universe inside. The breadth of the size of humanity is just staggering.
