W: Hi, Martin. How are you? M: Fine, but busy. We've got some exams next week, remember? W: I know. How much work did you do last night? M: None. I went to the cinema. What about you? W: I had no time last night. It was my sister's birthday, so we all went out to dinner. M: Have you done any work this morning? W: Some, but not a lot. Anyway, I rang to ask you something. Do you know where my physics book is? M: I've got no idea, but you can borrow mine if you want. W: Thanks. M: Let's meet outside Natbank in High Street at lunch time. I'll bring my physics book to you. W: Good idea. I'm very worried about the physics exam. Have you got any old exam papers? I'd really like to look through them. M: I haven't, but my brother's got some. I'll bring them with me at lunch time. W: Wonderful! See you at 12:30. OK?
