Professor, could I make an appointment with you?
I am free tomorrow afternoon between two and four ; do you have a particular time in mind?
Two o'clock would be the best time.
Fine, do you know where my office is?
No, I'm not sure.
Remember, it is in the E building on the third floor.
I see.
Don't worry, it will work out fine once you get there. I'll see you then.
I'll see you then.
Looking forward to meeting with you!
