text: Ellie: Morning!
  Andrew: Morning!
  Ellie: Have you ever been in Prague and/or be able to suggest places that we should visit there?
  Andrew: Nope and nope. But I could ask my sister, she travels a lot and probably already been there.
  Ellie: I know that the city center (old city) in general is a nice place.
  Ellie: But we have only two full days, so I'm trying to maximize the amount of sightseeing.
  Andrew: You should be able to find some info on the Internet - like guides to cities/things you need to see.
  Ellie: Well, we have guides, I'm just asking suggestions from people which have similar likes than me. :)
  Andrew: Cities are difficult to grasp when travelling, there's so many things and places to visit. Just go where the biggest crowd is and suffer ;)
  Ellie: Big crowds = full of pickpockets. :)
  Andrew: And full of people, I don't like crowds in general :P
target: Ellie is going to Prague for two full days. Andrew hasn't been to Prague and can't suggest anything to see there.
