Input:  Person1:     Hi Mary , how's it going ? 
 Person2:  well , last night I had a big argument with Ann . 
 Person1:      terrible . It must be something serious . You two are such close friends . 
 Person2:  now that I look back at it , it wawsn't that big a deal . I shouldn't have lost my temper . 
 Person1:      really ? What happened ? 
 Person2:  it's just we've been planning to go the beach for a while , and we decided we could both make it this weekend . Then out of nowhere she called me up , said her boyfriend had made plans and that she nee 
 Person1:      that's pretty harsh . 
 Person2:  I know , but I was so upset . I mean , come on ! Does she have to do everything her boyfriend says ? 
 Person1:      you know she probably feels just as bad . 
 Person2:  well , I think I was being a little selfish myself . I know they don't get to see each other very often . 
 Person1:      well , in that case I guess maybe you can be more understanding . You shouldn't let a trivial thing like this stand in the way of your friendship . After all you can go to the beach anytime you want . 
 Person2:  yeah , I'll call her later to patch things up .
