Do you have girlfriend ?   Yes , why ?   Well , I came to know a girl three weeks ago . We have so much in common .   So ?   So I think I may fall in love with her .   That sounds great . But how do you know that's a crush or a real love ?   Then what's the difference between having a crush and falling in real love ?   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 .   That's what I do .   And you think about her all the time ?   Yes .   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 .   That's it . She likes dogs so much now , and I begin to love dogs .   Oh , congratulations . Sounds like you've found your soul mate .   Thanks , but I know falling in love is one thing while staying in love is another .   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 .
