Person2: Interesting . It must be great having a twin sister . Are you best friends , too ?
Person1: We used to be really close , but that all changed once she moved to Shanghai . How about your family ? You didn ' t mention to your biological father .

Example Input: 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 .
