City life

I live in the city. I go to work by Taipei metro everyday. All commutors are always in a hurry. If people don't want to walk on the elevator, they will stand on the right side of the elevator. Or they stand on the left side of the elevator and walk. When the doors of the train open, the outsiders will automatically let the passengers in the train go out, then they enter the train. No one make the rule. The commuters make the rules automatically.
  Sometimes I see some olds take the MRT during the rush hour. Other passengers sitting on the seat will immediately stand and invite the olds to sit. The old will thank them. People in Taiwan are so friendly.
