dialogue: Carl: Hey, Sis. Are you interested in buying some used books for school? You can really save some money that way. Ashley: Well, what do you have? Carl: Well, let's see. I have a science book called, Today's World, and I'm selling it for thirty dollars. Ashley: Thirty? That's a little expensive for a beat-up book like that. Carl: Maybe so, but I bought it for sixty. Plus, I wrote a lot of notes in the book that should help you with the class ... if you could read my writing. Ashley: What else are you selling? Carl: Okay, I have English writing textbook for fourteen dollars, a math book for twenty-three, and a novel for only seven bucks. Ashley: Uh, Hmmm. Carl: It's up to you. You know, these things go fast. I mean you have to listen to my advice as your older brother. Ashley: Psh. I'll take the English book and the novel. I need both of those for sure. I think I'll hold off on buying other books for now. [Okay.] Teachers are always changing their minds about textbooks. [Alright.] And, what are those books? Carl: Which ones? Ah, ah, nothing. Never mind. Ashley: Wait, wait, wait. Finding Your Perfect Someone. You're selling it for forty dollars? What's, what's this all about? And the price? Carl: Well. You .. It's a ... It's just a marital relations class. You know about finding a partner. You know, mom's always, you know, on me about that. What does it matter to you anyway? Ashley: Forty dollars? That's a little expense. Carl: Well, they guarantee results, but ah, never mind. You would never understand. Ashley: What about this one? Introduction to Gourmet Cooking? Why did you take this class? You hate cooking. Carl: Well, um, I have a friend who's into cooking, and she's [She?] ... I mean, my friend's taking the class. I mean, ugh, does it really matter? Ashley: A marriage class ... a close female friend ... a cooking textbook ... I think I get the picture. Mom's going to be excited about this. Carl: Ah, you got it all wrong. So, do you want to buy any of these textbooks or not?
