Quote context

[...]

- You forgot your hat, Miss Tracy. And you look lovely, Miss Tracy. All our very best wishes.

- Dexter, I do wish you'd let me know when you invite people to Tracy's weddings.

- Why? What happened, darling?

- A Mr. Sidney Kidd is here. He says he knows you.

- Sidney Kidd is here, himself?

- What else did Mr. Sidney Kidd have to say?

- Oh, he sent you the strangest message. He said, 'Tell Haven he wins. Tell him I'm licked.' Wins what, Dexter?

- Mr. Sidney Kidd's presence here makes the marriage of national importance.

- Well, I think it's extremely kind and thoughtful of him.

- Come on, Tracy. It must be late. Let's let bygones be bygones. What do you say?

- Yes, and good-bye, George.

- I don't understand you.

- Please, good-bye.

- You're too good for me, George. You're a hundred times too good. And I'd make you most unhappy, most... That is, I'd do my best to.

- Well, if that's the way you want it.

- That's the way it is.

- All right. Possibly it's just as well.
