When I took the underground back home from school, I noticed two things around me.
The first thing I met is about a boy The boy didn't feel well. He began to vomit. A beautiful girl saw the boy. She helped him clean the floor. Then the boy thanked her for helping. The second thing is about the underground. When the underground got to the station, a lot of people pushed towards the seat. So some people couldn't get off the underground. Some had a quarrel because of this.
In my opinion, The girl did a good thing and we appreciated her action in this society. As for the underground. It shows your quality there. If you wait in a line, others will get off the underground easily. If all of us can do in this way, our world will be more beautiful.
