text: Betty: Hi :-)
  Alice: Hi :-)
  Betty: Have you got the book which we need for the classes with Dr Oaks?
  Alice: Not yet. Do you?
  Betty: Not yet. I hoped you'd tell me where I can get it.
  Alice: Are there any problems?
  Betty: Seems like.
  Alice: How about the central library? I'd expect they must have a few copies.
  Betty: And here you are wrong. I've already tried.
  Alice: Oh...
  Betty: In local libraries as well. Nothing.
  Alice: And now what?
  Betty: Do you know anyone from the year above? Maybe they can help us?
  Alice: I know Tony. I'll try it with him.
  Betty: Let me know. 
  Alice: I will. Till later.
  Betty: Bye.
target: Betty and Alice need a book for classes with Dr Oaks. The book is hard to get. Alice will ask Tony about it.
