Здравствуйте, переведите, пожалуйста, этот диалог в косвенную речь! ОЧЕНЬ СРОЧНО!НА АНГЛИЙСКОМ!!- Welcome back, Bella! How was your holiday? - Hi, andrew. It was fantastic. It's a shame you didn't come.- Ok, don't make me jealous. Just tell me all about it. Well, greece was amazing. I took lots of pictures, but | got sunstroke. - How awful! - Well, i should have been more careful. Anyway, after greece, i went to italy, but i got seasick on the ferry. - Oh, poor thing! Hope it didn't spoil your holiday. - 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. - Yes, maybe next year. Did you manage to go to spain? - Yes, but i had a bit of trouble in Barcelona. - Really? What happened?- My purse was stolen while i was waiting for a bus. Luckily, there wasn't much money in it.- That's bad luck! - I know, but these things happen and i didn't let it spoil my holiday. - Good for you! anyway, the important thing is that you're back safe and sound, and you had a good time. That's true, and i'm thinking of going back next year if you're interested. - Sounds good!
