 Person2:  No . Really , what happened ?  
 Person1:      Well , it was all a big mistake , actually . He got home on Friday night really late , and apparently he'd been out drinking with some clients , so he was really drunk .  
 Person2:  Was he out with the guys from the bank ?  
 Person1:      Yes , I think so .  
 Person2:  Oh , yeah , they always get really drunk .  
 Person1:      Well , anyway , he'd somehow lost his wallet and his house keys , so he couldn't get in . He lives alone , you know .  
 Person2:  Oh , really . I thought he lived with his wife .  
 Person1:      No , she left him last year .  
 Person2:  Oh , really ? Do you know why ?  
 Person1:      Hang on , let me finish telling you what happened . Where was I ?  
 Person2:  He lost his wallet and keys .  
 Person1:      Oh yes , well , he tried to climb in through the bathroom window , but apparently he slipped and broke the glass with his foot . The neighbors heard him and thought a robbery was in progress , so they called the police .  
 Person2:  Oh , no .  
 Person1:      Yes . So when the cops arrived , they didn't believe his story  
 Person2:  So then what happened ?  
 Person1:      Well , when he sobered up , he called someone from work to come and bail him out .  
 Person2:  Well , that's a bit of a tricky situation .  
 Person1:      Yes , I know .
