What will the woman do tomorrow?

W: Oh, I’m sorry, Mr. Smith.
M: What’s up, Mary?
W: I’m afraid I can’t work overtime tomorrow. John and I are holding a party for the 5th anniversary of our wedding.
M: That’s all right. Enjoy yourselves.

W: Northwest Airways, good morning. Can I help you?
M: Yes, do you have any flights to Sydney next Tuesday afternoon?
W: Yes, there is a flight at 6:45 and one at 18:00.
M: That’s fine. Could you tell me how much return flight costs?
W: That would be 418 dollars.
