answer: #Person1# thinks she broke up with Mike because they aren't compatible in astrology. #Person2# thinks judging people by astrology is wrong while #Person1# thinks her case matches the theory.
documents: #Person1#: Now I know why I split up with Mike. We found we were simply not good for each other.
  #Person2#: In what ways?
  #Person1#: Well, he is a typical Sagittarius guy, while I am a Cancer. We aren't really compatible
  #Person2#: Ha-ha, so you believe in astrology?
  #Person1#: What's strange about that! As a person born under the sign of Cancer, I am home-loving and wish for a peaceful family life. But according to astrology, Sagittarius guys are too adventurous and risk-taking. They seldom think of leading a settled and peaceful life.
  #Person2#: Is that so? I'm afraid it is too narrow-minded to judge people using astrology. It's all stereotypes!
  #Person1#: But in my case, the fact matches the theory. Mike is humorous, energetic, always as fresh as a daisy, but probably too ambitious. It frightens me!
  #Person2#: But as far as I remember, you two caught on like a house on fire when you first met.
  #Person1#: Exactly. But later on, he cares more about his career than love. Work seems to be the better all, and all for him-so much that he doesn't even grudge sparing a day out with me.
