One day, a girl was called to the teacher's office. The teacher said, "Be my undercover and help me find out the secrets in the class." The girl began to hesitate. Then the teacher said, don't forget, it is worthwhile to help the teacher or the people who will compete with you for different roads in the future. It is worthwhile for the girl to think about it. You see how proud you are, she readily agreed, and she will say whatever the teacher asks her in the future. Gradually, the teacher didn't ask her again, and she also reported to the class diligently. The director didn't know on May Day. She watched her classmates being scolded and questioned by the teacher, gnashing her teeth, but she couldn't find the mole. I was quite carefree for a long time. The classmate who was always exposed in the class couldn't sit still and decided to find out the hateful traitor until one day the girl went to the office to report the situation again. A classmate heard the news and spread it, saying that the girl was having a hard time. She was slapped by other girls in the class, spurned and insulted by boys, and bullied and insulted. One day, she finally lost her anger and rushed to the office to find her class teacher. You killed me! If you hadn't sent me undercover, look how miserable I am today! I hate you! "The teacher smiled:" Ha ha, you don't know. Before you, I asked more than 20 classmates, and they all flatly refused, but you didn't refuse. I am willing to be what they call a traitor. They scolded me for arranging undercover. I don't know. Remember, teachers don't hate spies as much as you did when you were a student. Who can you blame for coming out? "When you go to prison, don't blame the person who dragged you to steal just because you volunteered. Please look at the dogs in the class carefully.
