M: Mary, I hope you are packed and ready to leave.
W: Yes, I’m packed, but not quite ready. I can’t find my passport.
M: Your passport? That’s the one thing you mustn’t leave behind!
W: I know. I haven’t lost it. I’ve packed it, but I can’t remember which bag it’s in.
M: Well, you’ll have to find it at the airport. Come on! The taxi is waiting.
W: Did you say taxi? I thought we were going in your car.
M: Yes, well, I had planned to, but I’ll explain later. You’ve got to be there in an hour.
W: The plane doesn’t leave for two hours. Anyway, I’m ready to go now.
M: Now, you are taking just one case, is that right?
W: No, there is one in the hall as well.
M: Gosh, what a lot of stuff] You are taking enough for a month instead of a week.
W: Well, you can’t depend on the weather. It might be cold.
M: It’s never cold in Rome. Certainly not in May. Come on, we really must go.
W: Right, we are ready. We’ve got the bags, I’m sure there is no need to rash.
M: There is. I asked the taxi driver to wait two minutes, not twenty!
W: Look, I’m supposed to be going away to relax. You are making me nervous!
M: Well, I want you to relax on holidays, but you can’t relax yet.
W: OK, I promise not to relax, at least not until we get to the airport and I find my passport.
