Input:  Person1:     Hi , Larry , how was your weekend ? 
 Person2:  Not bad . We had a get-together with friends from college . I haven't seen many of them since graduation . How about you ? 
 Person1:      Great . I hung out with Jo all day shopping , and the went out for dinner together . 
 Person2:  Sounds a good weekend . You know it always amazes me that two people as different as you and Jo can become such close friends . 
 Person1:      Yeah , I never thought we could be good friends either . We have our differences . She's more outgoing and active while I am more quiet and reversed , but we still get along extremely well . We can talk for hours about anything . 
 Person2:  That's great . I know people who can't stand each other for even five minutes . 
 Person1:      When Jo and I are together , we argue a lot , but that's also part of the fun . Besides , I know she will always be there for me when I need her , and she knows I'll be there for her . 
 Person2:  It seems you two bring out the best of one another . 
 Person1:      Exactly . Having Jo as my friend is one of the best things that's ever happened to me . 
 Person2:  Yeah , you are so lucky to have found each other . 
 Person1:      Thanks , I think so too .
