    Jane was on her way home at around 6 o'clock. It was getting dark. As she drove into her community, she noticed a man.

    She saw the man walking along the sidewalk next to some houses. He didn't live in any of those houses. She had seen this man several times before. He looked like a criminal (罪犯).

    She drove by him. He looked at her car as she drove by. She continued driving and watched him in her rear view mirror (后视镜). She got to the corner and stopped. She continued to watch him walking in her direction. Suddenly, he turned left up a driveway (车道). A red SUV was parked in the driveway right next to the sidewalk. She saw him walk up to the driver's door and put his hand on the handle (把手). Then he returned to the sidewalk and went on to walk in her direction.

    "What is that all about?" Jane wondered. Then she realized that he had tested the door to see if it was locked. "He is a criminal," she thought. "That's what he does. He just walks in our neighborhood looking for cars to break into."

    She called the police and described the man. The police officer said he knew who the man was. The people in the community called two or three times this week to report him walking by. But the police couldn't arrest him for walking around unless they caught him with stolen things. "But he was testing that SUV door to see if it was unlocked," she said.

    "I'm sorry," said the officer. "That's not against the law. If you see him actually steal something, please give us a call."

B

    I'm David. Long ago I came to the city near my hometown to find a job. I met all kinds of difficulties and I used up all my money soon.

    It was dark outside one day. I got on a bus quietly. Suddenly, a passenger cried in a loud voice, "someone has stolen my money!" I felt nervous, because his money was in my hand. Some people suggested the driver drive the bus to the police station, but some were against it because they were in a hurry to go back home. The whole bus was very noisy. The driver then stopped the bus by the roadside and turned on the lights. At that time, one passenger said, "Turn off the lights and give the thief(小简)a chance to take out the money."Then the bus got dark.

    When I was still thinking about whether to take out the money or not, the lights were turned on again. There was no money on the floor. Someone said, "Give him one more chance." Then the lights were turned off again. I became even more nervous. The lights were turned on again but they got the same result.

    Then the passengers fell into an open discussion. Later, someone said, "Give him the last chance!" I felt awakened(醒悟的) and took out all the money when the lights were turned off again.

    For many years I have been grateful to those who gave me three chances. When the first and Second chances come, you may not be prepared well or don't have enough courage to act. When the third chance comes, you should know clearly what you should do.
