Culture differences

On the subway today (I had a meeting in a different location, so I took the subway instead of the bus), and I noticed something interesting.

On one of the cars on my way home, there were a few people sitting along one side.

My preference is to sit as far away from anyone else I could get.

Several times now, I've noticed that Koreans tend to like to be together, whether they know each other or not. And I watched a person come on the car, look around, and pick a seat.

Right between two already seated people.
