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 wasn'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 need to cancel the trip . I was so angry when she told me that I said she didn't care about our friendship at all .  
 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 later to patch things up .
