Andrew: Welcome back, Bella! How was your holiday?
Isabelle: Hi, Andrew. It was fantastic. It's a shame you didn't come.
Andrew: OK, don't make me jealous. Just tell me all about it.
Isabelle: Well, Greece was amazing. I took lots of pictures, but I got sunstroke.
Andrew: How awful!
Isabelle: Well, I should have been more careful. Anyway, after Greece, I went to Italy, but I got seasick on the ferry.
Andrew: Oh, poor thing! Hope it didn't spoil your holiday.
Isabelle: No, not at all. Italy was fantastic! The people are very friendly and I loved Italian cuisine. You have to go to Rome some day. It's beautiful.
Andrew: Yes, maybe next year. Did you manage to go to Spain?
Isabelle: Yes, but I had a bit of trouble in Barcelona.
Andrew: Really? What happened?
Isabelle: My purse was stolen while I was waiting for a bus. Luckily, there wasn't much money in it.
Andrew: That's bad luck!
Isabelle: I know, but these things happen and I didn't let it spoil my holiday.
Andrew: Good for you! Anyway, the important thing is that you're back safe and sound, and you had a good time.
Isabelle: That's true, and I'm thinking of going back next year if you're interested.
Andrew: Sounds good!
