Quote context

[...]

- José da Silva Pereira.

- Who the hell's José da Silva Pereira?

- Darling, you met him. I know you did. Mag Wildwood's friend. The tall, good-looking one who came to the party with Rusty?

- Well, my dear, you won't believe this, but it turns out not only is he handsome and wildly rich, he's absolutely cuckoo for me.

- You're crazy.

- What? Do you think you own me?

- That's exactly what I think.

- I know, I know. That's what everybody always thinks, but everybody happens to be wrong.

- Look, I am not everybody. Or am I? Is that what you really think? That I'm no different from all your other rats and super-rats?

- Wait a minute. If that's it, if that's what you really think, there's something I want to give you.

- What's that?

- $50 for the powder room.

- I wouldn't ask you in, except the place is in such a mess I couldn't bear to face it alone.
