A: M: Are you really leaving for Hongkong tomorrow morning?
Problem: Given the question: W: Pardon? M: The book! You haven't turned the page in the last ten minutes. W: No, Jim, I suppose I haven't. I need to get through it, though, but I keep drifting away. M: So it doesn't really hold your interest? W: No, not really. I wouldn't bother with it, to be honest, but I have to read it for a seminar. I'm at a university. M: It's a labor of labor then rather than a labor of love. W: I should say, I don't like Dickens at all really, the author, indeed, I am starting to like the whole course less and less. M: It's not just the book, it's the curse as well? W: Yeah, in a way, although the curse itself isn't really that bad, a lot of it is pretty good, in fact, and the lecturer is fine, as to me, I suppose, you see, I want to do philosophy rather than English, but my parents took me out of it. M: So the courses are OK as such, it's just that had if been left to you, you would choose a different one. W: Oh, they had my best interest and heart of course, my parents, they always do, don't they? They believe that my job prospect would be pretty limited with the degree of philosophy. Plus, they give me a really generous allowance, but I am beginning to feel that I'm wasting my time and their money. They would be so disappointed though if I told them I was quitting.
