answer: #Person1# tells #Person2# #Person1# may fall in love with a girl and #Person2# helps #Person1# figure out it is a real love instead of a crush. #Person1# understands that falling in love and staying in love are different.
documents: #Person1#: Do you have girlfriend?
  #Person2#: Yes, why?
  #Person1#: Well, I came to know a girl three weeks ago. We have so much in common.
  #Person2#: So?
  #Person1#: So I think I may fall in love with her.
  #Person2#: That sounds great. But how do you know that's a crush or a real love?
  #Person1#: Then what's the difference between having a crush and falling in real love?
  #Person2#: That's a big question. Well, if you're in love, maybe you will take every opportunity to talk to her or telephone her for no reason at all.
  #Person1#: That's what I do.
  #Person2#: And you think about her all the time?
  #Person1#: Yes.
  #Person2#: And maybe you suddenly have new interests. I mean you suddenly begin to do things you used to avoid. For instance, you used to sleep in every morning, but because she jogs every morning then you begin to like jogging.
  #Person1#: That's it. She likes dogs so much now, and I begin to love dogs.
  #Person2#: Oh, congratulations. Sounds like you've found your soul mate.
  #Person1#: Thanks, but I know falling in love is one thing while staying in love is another.
  #Person2#: Yes, that's right. If you find this person becomes more and more important to you and you can totally trust her, then you can stay in love.
  #Person1#: Yeah, falling in love is so good.
