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.
