to music without looking at them. Some w ill turn their faces to look out of the windows. Even when the bus driver keeps asking people to help the old, they just sit on the
seats. These people are not kind or friendly.
However, we should help each other because everyone needs others’ help. Next time, please be polite to help the person who needs help on the bus. You can let the old
people get on or get off the bus before you, or give your seats to the people with
children. Then all the people will live a happy life.
