Hi, Mark.

It's Mary.

I hope you have not forgotten that we arranged to play tennis this afternoon.

Of course not.

I'll see you then.

How long do you think it will take to repair this phone?

to tell, but we should have it ready for you by three o'clock.

Why do I have to put out my cigarette?

This is a non-smoking flight, sir.

Actually, all our flights are non-smoking.
