dialogue: Daffie: What about taking a tour around Cambridge today?
  Yolande: I did that with a friend yesterday.
  Daffie: But didn't you say you would go to the London Eye yesterday?
  Yolande: My friend had already been there, so I changed my plan. Today I want to see some modern art work.
  Daffie: If so, you can go to Tate Modern. It's a museum with a collection of international artwork from the nineteen hundreds.
  Yolande: Do many people visit it?
  Daffie: Yes, it's very popular. But don't worry, it's usually not crowded on weekdays. If you go tomorrow though, there're maybe a lot of people.
summary: Daffie suggests visiting Cambridge, but Yolande went there yesterday. Yolande wants to see some modern artwork so Daffie recommends Tate Modern.
