Tony is a good student. At school, his teachers like him very much because he never disrespects or disobeys them. But Tony was unhappy and was unable to sleep at night for a whole week. He told his best friend Jack. “Last week, Miss Black asked me to lock the classroom door. But I was rushing to my basketball training and forgot about it. Would she discover it?”, said Tony non-stop in a worried voice. Jack said, “What nonsense are you talking about? I was taking a nap under the desks last week. You probably didn’t see me. But don’t worry! I’ve locked the door before leaving.”
