 Person1:      Sounds quite fruitful , why do you call it still a nightmare then ?  
 Person2:  Well , the air line lost my luggage on the return flight and then I lost my carry on bag when I was tackling with the officers in charge . I left the airport three hours later than I expected and then I was caught in a traffic jam . When I finally got home , I was totally exhausted . But I found the elevator was out of service due to a blackout .  
 Person1:      This is really a sad story . Did they trace back your luggage ?  
 Person2:  I am still waiting for their call .
