Hello, Mr. Johnson, how are you?

Fine, thank you, and how are you?

Pretty good. What can I do for you today?

Well, I'm having several friends over for dinner this Friday,

    and I was wondering if you have the time to join us.

Sounds interesting. What time would you like me to come?

Is six o'clock all right?

That's fine, I thank I can make it.

Very good, I'll see you Friday. Good-bye.

Thanks for calling. See you then.
