                                                                    Offer a Seat

     One day, a boy and his mother were sitting on the bus when a granny with grey hair got on it. The granny

with a walking stick was carrying a big basket. The bus was full of people and there was no seat left. A young

man who was smoking and a young lady with a hat pretended not to see the granny. "Cranny, sit here, please."

Following the voice, people saw a little boy with a round face. He was only three or four years old. He pulled

the granny to his seat and asked her to sit down.

     Seeing this, the boy' s mother was pleased. The people in the bus smiled happily. They praised the boy for

his good manners. But the young man and the young ladyfelt very sorry. Their faces turned red.
