M: Dr. Bezel speaking.
W: Hello, Professor Bezel. This is Janet Bob calling. My roommate, Jim McLean, is a graduate assistant in your department. Jim asked me to call you because he has a throat infection and he can’ t talk to you himself.
M: A throat infection? That’ s pity. Is there something I can do to help?
W: In fact, he has class this afternoon from 1: 30 to 3 ;00, and he won’ t make it.
M: Is he looking for a substitute?
W: No, that wouldn’ t be necessary. What he wants me to do is find someone to go in and play a ninety-minute wildlife videotape about native North American rodents.
