Problem: M: Sorry, Miss. I didn't mean to do that, but it was my alarm clock that didn't wake me up. W: That is not a proper excuse. You could set it ahead of the exact time so that you could have got up earlier and not have been late. M: I did that, but it seemed useless when I found the batteries had run out after I woke up this morning. I rushed to school and luckily, my neighbour Mr. Green gave me a hand and took me to school with his car. W: So you could have made it. But you were still late for class. M: The thing is, when I got off, I found I had left my bag in his car. And it was too late to get it back when I realized that. I went straight to the nearest shop and gave him a call. I waited for five minutes before Mr. Green drove back. W: Finally, he gave you your bag and you came to the classroom and you were already 15 minutes late for class at that time. Is that all? M: Miss, you seem to know the entire story. May I go back to class now? Otherwise I will be late for the following class. What was said before this conversation?

A: W: Come to my office, Billy. Look at your messy hair. This is the third time you have been late for class within this week. And every time you went in, you disturbed the teacher's class.
Problem: Given the question: Neighbor: Listen. Even though the trees are in your yard, some of the branches hang over into mine, and I am getting sick and tired of raking up your leaves and picking up all the branches that fall off during storms throughout the year. And the walnuts off this tree ... they litter my yard and damage my lawnmower when I cut the grass. And my dog eats them, and he ends up with terrible diarrhea. Man: Still. You can't cut off those branches. Neighbor: Watch me. It's completely legal. I check the city code and law regarding this issue, and I am well within my rights. Man: I'm not sure about that. Anyway, It's just not right. You didn't say anything to us about it ... Neighbor: I don't have to. Man: Yeah, but you could have said something. Anything! I mean I want to stay on friendly terms with you, but the basic courtesy of informing your neighbors is the least you could have done. Neighbor: Okay. I'm cutting down your branches. You've been informed ... now, stand back! Man: Hey. Don't expect an invitation to our next barbecue or book club! Neighbor: See if I care. Hey, what are you doing? Stop shaking the ladder. You're acting juvenile now. Help! What was said before this conversation?

Then he does his homework after tea. It often takes him a couple of hours to finish it. M: Poor boy. They work hard at school nowadays, don't they? Does he like it? W: You mean the school? Yes, he does. He likes his teachers and classmates. M: Does he go to school by bus? W: No, he walks. He likes walking. He meets some of his friends at the corner and they go together. M: What does he do when it rains? W: My husband takes him in the car. He passes the school on the way to the office. What was said before this conversation?
