The Beets were a new couple. Mr Beet worked in an office. He worked hard so that he was paid more. The things in the rooms, such as the television, the computer, furniture and so on, were all left by his parents. They only paid some money for their food and clothes. But they tried their best to save money. If they had something important to tell their friends, they preferred to visit them than call them. Sometimes one of them felt sick, they bought some medicine instead of seeing a doctor.
One day, it was a quarter past nine. Mr Beet didn't come back. His wife was worried. The supper was cold and she had waited for two hours and a half. She was sitting by the table in the dark room.
Suddenly the woman heard someone coming. She hurried to open the door. In the dark she could hear his deep breathing. As soon as he sat down, she turned on the light and found he looked very tired.
"Why do you come back so late, dear?"asked the woman, "Haven't you caught a bus?"
"Yes, but I didn't take it."
"Yes? But why now?"
"I ran after it so that I saved two dollars this evening."
"That's great!" the woman said happily, "Run after a taxi next time and you'll save both more time and money!"
