Paul got on the bus to go to the town. It was very crowded, and he had to stand for about five minutes.
Then some of the passengers got off. Paul sat down next to a fat lady. She had several shopping bags, and
Paul didn't have much room on the seat. At last the bus got to the town. All the passengers started to get off.
Paul was very polite, so he stood up to let the fat lady get off before him. She said, "Thank you." Then she
tried to get out of the seat with all her bags. But she couldn't move. She was stuck!
Paul had to push the lady. The conductor pulled her. Finally they got her free but she wasn't pleased.
"I'll write to the bus company," she said. "I'll tell them not to make buses with such small seats."
