Hi , Francis , how was your business trip ?   It was a nightmare .   What ’ s up ?   Actually , the business trip itself was very successful . We arrived on time , we had nice conversations and we settled some important issues for the next year .   Sounds quite fruitful , why do you call it still a nightmare then ?   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 .   This is really a sad story . Did they trace back your luggage ?
