[Q]: W: Yeah, I went to Qingdao and just came back yesterday. M: Really? Did you go to see the Qingdao Olympic Sailing Center? I thought you were just shooting the breeze when you said you would go. How is it? W: It's really amazing. During the 2007 Qingdao International Sailing Games, around 5,000 people came out to watch the competition every day along the seawall. M: Newspapers say the design received high praise from the International Olympic Committee. The venue will be used for the 2008 Olympic Games. W: Fortunately, I have been there already. It's a pity you're not going to see it. M: Although I know my chances of getting an Olympic sailing ticket are slim, I'll keep trying anyway. Otherwise, I'm sure you'll nag me to death telling me about your experience there. What was said before this conversation?

Please answer this: W: The sociology text professor Smith uses in his course. M: You had better read it if you want to pass the course. W: But it is too expensive. I simply can't afford it. M: How much does it cost? W: It costs 40 dollars. M: Did you check the used book section here? Maybe they have one. W: No, they don't. I have asked. M: Why don't you get it from the library? W: Are you joking? I've been trying for months and the book is always out. There are more than 45 students in the course and every single one wants the book. M: Listen, you know my roommate, Henry, don't you? He took the same course last year and I believe he owns the book. I'll ask him if he'll lend it to you. W: Oh, Tom, that would settle everything. That's very kind of you. M: My pleasure. What was said before this conversation?

The answer is:
M: Which floor do you live on, Edison?
Problem: M: OK. I watch people a lot. I do that when I travel. I've been to many countries such as Britain, Italy and Sweden. So I spend a lot of time at airports. While waiting for my flights, I watch people passing by and start my imagination. For example, the other day, when I was waiting for my flight to Greece, I saw a couple. They were buying magazines at that moment. They were not wearing business clothes, but the man was carrying a suitcase. Every few seconds, the woman looked around. I wondered if someone was following them. Perhaps they were running away, and you know, this reminded me of a story in the newspaper that day: a bank clerk stole one million pounds a week before and disappeared with his wife. There was a picture of them in the paper. The couple really looked like the wiz. Maybe I should stop them. Just then, I saw them say goodbye to each other, and the woman walked away. Well, sometimes I make mistakes like that. But I find things like that are very useful for my writing. What was said before this conversation?
