I'd like to see you off, Jane, but I can't get to the airport until five o'clock.
I'm afraid I'll have left by then. My plane takes off at 4:30.
What a pity! You're going straight to Washington, aren't you?
No, I'm staying with my sister in New York. She isn't there at the moment but she'll have arrived by Monday morning. I'll spend a couple of weeks with her and then go to Washington. Classes will already have started by then.
