Input:  Person1:     It's a lovely day , isn't it ?  
 Person2:  Yeah , and most excitingly , I met the girl living under me today . She's really nice .  
 Person1:      Is she American ?  
 Person2:  Yeah , and most importantly , she's single ! Man , I could tell from the moment I saw her , she's the girl of my dreams !  
 Person1:      So I take it you two are hitting it off ? I know it's very convenient to be in a relationship with your neighbor , but what if you break up ?  
 Person2:  I don't know . I am not really worried about that . I don't wanna lose before even starting . Besides I think the other two American guys have also fallen for her .  
 Person1:      Sounds like you've got some competition . You made a move already ?  
 Person2:  Not yet . But I am thinking of inviting her to dinner sometime . I know some good restaurants nearby .  
 Person1:      That's nice . Having been here a little while surely gives you the advantage , eh ?  
 Person2:  You bet . Now that you mentioned it , I think I'll call her now and see if she is available tonight .  
 Person1:      Good luck !  
 Person2:  Thanks !
