Hello, Mr. Black, I'm calling to say goodbye.
You're leaving so soon? I wish you stayed a little longer.
I wish I could stay a little longer, but a lot of things to do back home.
Have you got the ticket?
Yes, I did.
What time are you going?
At 11:00 o'clock.
I'll pick you up by nine o'clock and take you straight to the airport.
No, I'll go by myself, thanks.
OK, goodbye.
