Input:  Person1:     I had a terrible journey back from Bangkok last week . 
 Person2:  Really ? Why ? What happened ? 
 Person1:      Well , first of all , the taxi that was taking me from the client's office to the airport broke down on the freeway . 
 Person2:  Oh , no . 
 Person1:      Yes , and the driver didn't speak any English or Chinese and he didn't have a phone on him-can you believe it ? - and his radio didn't work . So there was no way he could get in touch with the office to get them to send another taxi . 
 Person2:  So what did you do ? 
 Person1:      Well , I actually thumbed a lift . 
 Person2:  You what ? 
 Person1:      Yes , I stood on the side of the freeway and stuck my thumb out , and a passing truck stopped and took me to the airport . 
 Person2:  Wow , good for you . 
 Person1:      Yes , except he drove really slowly , and I missed my flight . 
 Person2:  Oh , no ! 
 Person1:      Yes , so I had to wait three hours for the next one . I didn't get home till four in the morning , and when I got home I realized I'd left my house keys in my hotel in Bangkok . 
 Person2:  You really have bad luck , don't you ? 
 Person1:      Seems like it .
