Input:  Person1:     What did you do at the office today ?  
 Person2:  I had a really busy day . I had to work a little overtime . In the morning an important client called to place a large order . I had to check some things with my colleagues before confirming the order .  
 Person1:      What kind of things did you need to check ?  
 Person2:  The most important thing was to check that we had the goods in stock . If the goods are in stock , we can deliver them immediately . I also had to check the price . This customer is very important , so they get special prices .  
 Person1:      I see . Did anything else happen ?  
 Person2:  I received a lot of emails from potential clients that I had to answer . Each time , I had to check files to see what we had agreed at earlier meetings . Each client has different conditions and requirements .  
 Person1:      It must be difficult to remember the details for each individual client .  
 Person2:  Yes . That ’ s why we have everything on computer files . We don ’ t use much paper at our office . After lunch , I had to deal with a complaint from a client .  
 Person1:      I hate dealing with complaints . Was it a legitimate complaint ?  
 Person2:  Yes , it was . I managed to sort out the problem , but I was tied up with the matter for over an hour .  
 Person1:      You certainly had a busy day .  
 Person2:  That ’ s not all ! I also had to finish writing a sales report for my boss . In the end , I finished everything . I wonder what will be waiting for me tomorrow morning .
