in a hotel. on the 4th floor. went down to the lobby. some new guests arrived. one middle aged woman wanted to see how the rooms were on the 4th floor. I offer to lead her. pushed the button of elevator. she mentioned she and others were from wuhan, so I asked her and she said that we were of one tour group. You are also from Wuhan, she said. on the 4th floor, she went to check the rooms. I then was surrounded by lots of kids wearing school uniforms. One kid was bigger and taller than others. I asked about his grade and they said they were in the same grade.they were laughing and talking.
