dialogue: Rod: Hello, Barbara, welcome back. You look great.
  Barbara: Rod, it's lovely to see you again.
  Rod: How was your trip?
  Barbara: Fine but tiring. Milan was interesting, it's bigger than I expected, noisier and dirtier, too.
  Rod: And Florence, what did you think of Florence?
  Barbara: Well, I didn't go there. Have you been there?
  Rod: No, I've never been to Italy. I'd really like to go to Roma. Well, the cars are in the car park. Is this all your luggage?
  Barbara: Yes, but the suitcase is very heavy.
  Rod: Barbara, what's in it? Books or stones?
  Barbara: Just 20 pairs of shoes.
