Lesson 139: Is that you, John?

Is that you, John?

GRAHAM TURNER:	Is that you, John?
JOHN SMITH:	Yes, speaking.
GRAHAM TURNER:	Tell Mary we'll be late for dinner this evening.
JOHN SMITH:	I'm afraid I don't understand.
GRAHAM TURNER:	Hasn't Mary told you? She invited Charlotte and me to dinner this evening. I said I would be at your house at six o'clock, but the boss wants me to do some extra work. I'll have to stay at the office. I don't know when I'll finish. Oh, and by the way, my wife wants to know if Mary needs any help.
JOHN SMITH:	I don't know what you're talking about.
GRAHAM TURNER:	That is John Smith, isn't it?
JOHN SMITH:	Yes, I'm John Smith.
GRAHAM TURNER:	You are John Smith, the engineer, aren't you?
JOHN SMITH:	That's right.
GRAHAM TURNER:	You work for the Overseas Engineering Company, don't you?
JOHN SMITH:	No, I don't. I'm John Smith the telephone engineer and I'm repairing your telephone line.
