Answer: M: By the way, do you know what time it is?

W: I don't feel good. I have a bad headache. In fact, I haven't got much sleep this past week, and I feel really tired. M: Why don't you go to see a doctor? W: Yeah, I think I should. But I have a report due tomorrow. Ms. Jenkins needs it for the board meeting next Monday. M: Well, it's Wednesday today. Why don't you talk to Ms. Jenkins, and ask if you can hand it in on Friday morning? W: Maybe I should try. I guess I just need a good sleep. Thanks, George. M: If you need any help with the report, just let me know. What was said before this conversation?
