W: Can I help you?
M: Yes,[20]I’d like to read some articles that are on reserve about British culture.
W: Professor Grand’s class?
M: That’s right. How could you know?
W: Let’s just say you are not the first person coming in asking for those articles.
M: Oh, well, it seems that I haven’t read any of them yet. It doesn’t really matter which one you give me first.
W: I’m afraid I can’t give you any of them at the moment. They’ve all been checked out.
M: You’re joking, all of them?
W: Every month. I’ve asked Professor Grand twice already to bring in additional copies of the articles, but no sooner do I place them on the shelves than they are gone. See that girl in the black sweater? She’s been waiting for half an hour for those same libarian, articles to be returned.
M: And here’s me. I went out of my way to free out the whole afternoon to read.
W: I’m sorry, but there is not a whole lot I can do about it. All I can suggest is that you come in first thing tomorrow morning and try again. We open at eight.
