#Person1#: Mary, when we get out of the elevator, could you call the repair shop to ask if my car has been repaired? I'm going into a meeting right away, so I don't have time to call them.
#Person2#: Sure, Mr. Walters. By the way, if your car is still being repaired, how are you going to get to work tomorrow? Is your wife going to take you?
#Person1#: No, she goes in a different direction.
#Person2#: I can call a taxi for you if you want.
#Person1#: No, thanks. I'm considering taking the bus.
#Person2#: That might be a good idea. You could get off right in front of our building and you wouldn't have to worry about parking.
