Excuse me, Professor, is there a time when I could meet with you?
I could meet with you tomorrow anywhere from two until four ; what time works out best?
I would like to come in at three o'clock.
I am glad that that works out ; can you find my office?
Yes, I can.
Just follow the walkway to the outside and climb the stairs to the third floor.
I got it.
If you do get lost, just ask someone in the building to point the way.
Thank you, I'll be there.
If you need to cancel your appointment, please give me a call!
