I heard that Bobby got fired?
Leslie:
Fired?
Pat:
I heard he was let go because of a drop in sales.
Chris:
Yes, the sales he's supposed to be making.
Leslie:
But everyone's sales are down.
Pat:
He said he was having a good quarter.
Chris:
Good? His sales are down even more.
Leslie:
Down more than what?
Pat:
Maybe they're just down relative to last year, which was a
good year for everyone.
Chris:
I think they're down relative to everyone else'.
Leslie:
Maybe it was something else. I heard he was drinking too
much.
Pat:
I heard because he couldn't take his boss's stupidity.
Chris:
Actually, his boss is brilliant. Bobby's the problem.
Leslie:
This doesn't add up.
Pat:
Well, it does add up. Maybe the truth is somewhere in
between everything we've said. You just need to add it
together.
