  Amy: When is it exactly?
  Samuel: End of May, 22nd I believe
  Amy: Ok, than we could have a garden party at my place
  Samuel: that's a great idea
  Amy: It should be warm enough already
  Samuel: Sure, and very green
  Amy: and about the present...
  Samuel: Any ideas?
  Amy: I think we could buy her a ticket for a concert
  Samuel: only us or also others?
  Amy: We can collect some money from her friends 
  Samuel: What concert?
  Amy: She loves Beach House and they are touring right now
  Samuel: Maybe we could buy her a ticket and a flight to some nice city where they are playing.
  Amy: Perfect idea
  Samuel: I'll check the tour and connections and let you know
  Amy: Ok! Thanks for that
target: Amy will organize a birthday party for Ann in her garden. Samuel will check Beach House's tour in order to buy Ann a concert ticket together with a flight ticket as a birthday present.
