- Did she sing this song? Who is she? Do tell me about her.

- She died many years ago, when you were only a little girl.

- Did you love her very much, Dorian?

- Yes.

- Goodbye, Dorian. I'm looking forward to your party tonight. I'm sure it will be wonderful. Your parties always are.

- I'm not really as lovely as that picture, am I, darling?

- Of course not.

- I think I've discovered why Dorian hasn't proposed to me. And I've decided what to do about it.

- And what have you decided to do about it?

- I'm going to ask him to marry me, tonight, perhaps.

- What about David Stone? You think he'd take you to Dorian's party tonight if he knew what your intentions were?

- Of course he would.

- Nothing petty about David, but I don't intend to tell him.

- No, don't tell David.

- David, you cad. I never thought you'd be an eavesdropper.
