It's Monday. The students are having an English class. The teacher is speaking. But Tom and Jack are not listening to the teacher. They are talking loudly. The other students can't hear the teacher. They are very angry. They say to Tom and Jack angrily, "Please do not talk. We are having a class. We can't hear our teacher. You are not polite. Please listen to the teacher carefully." Tom and Jack answer, "Sorry. We are wrong. "
