  #Person2#: Good morning. Could you help me please? I'm looking for some books for my mother.
  #Person1#: OK. What kind of books is she interested in?
  #Person2#: She's very fond of romantic love stories.
  #Person1#: I see. What about this one? Has she read it before?

  #Person2#: She'll be 90 next year.
