M: Physics Department, Doctor Benson speaking.
W: Hello, Prof. Benson, this is Natalie Kent calling, I’m living next door to your teaching assistant, Ashley Lake. Ashley asked me to call you because she has lost her voice and can’t talk to you herself.
M: Lost her voice? Oh, what a shame! Is there anything I can do for her?
W: Well, she has a class this morning from 10:00 to 11:00 and she won’t be able to teach it, but she doesn’t want to cancel it either.
M: Want me to try to find somebody else to teach the class?
W: No, not exactly. What she wants to do is to get someone just to pass back the mid-term exams. She’s already marked them and they are on the desk in her office. The whole thing wouldn’t take more than ten minutes.
M: Her class from 10:00, eh? Well I think at that time I was going to be on campus anyway: so I could do it for her. What room is her class in?
W: Wisdom Building, Room 301. Will you need her office key to get the exams? She’s given it to me and I could bring it to you.
M: Actually, that won’t be necessary. We have a master key in the physics department. So I can get into her office.
W: Thank you very much, Prof. Benson. Ashley doesn’t have another class to teach until Friday, and hopefully, she will be able to talk by then. She’ll call you as soon as she can.
M: Thanks for passing all the news about Ashley, and please tell her not to worry about anything.
