W: Have you had your holiday for this year yet, Jack?
M: Not yet. I’m taking it at the end of September.
W: Where are you going? Have you made up your mind?
M: Not really. I thought of going to Spain again, but I’ve already been there twice and I’d like to try somewhere new.
W: My brother’s just gone to Mexico for two weeks. I had a card from him yesterday and he seems to be having a good time. Why don’t you go there?
M: That’s O.K. for you well-off people, but I couldn’t possibly afford it. I’m much too hard up at the moment.
W: The air-fare is quite expensive, I admit, but you needn’t spend a lot when you get there.
M: I’ve already spent a lot of money this year. My flat was done up last month, so I haven’t got much to spare for expensive holidays abroad.
W: Oh, I see.
M: Perhaps I’ll just go to Scotland or Ireland in the end. I’ve heard they’re both very beautiful, and I haven’t been to either of them.
W: We went to Ireland two years ago to pay Mary and her husband a visit. They’re in Dublin now.
M: Oh, yes, so they are!
W: If you decide on Ireland you can call in on them. Mary would willingly put you up for a few days, I’m sure.
M: That’s a good idea! I haven’t seen Mary for more than three years and I’d like to know how she’s getting on.
