- W: Thank you. Professor Webster.

　　- M: My pleasure.

　　- W: Don doesn’t have another class to teach until Thursday, and hopefully he’ll be able to talk by then. He’ll call you as soon as he can. Oh, and…uh…I almost forgot…

　　- M: Yes?

　　- W: Could you put the next assignment on the board too? They should solve the equations at the end of chapter eight, and that’s due at the next class.

　　- M: Okay. No trouble at all. Thanks for the news about Don, and tell him not to worry about this.
