Quote context

[...]

- If I meet your friend inside, I'll be glad to give him a message for you.

- Would you do that for me? I certainly would appreciate that.

- Just tell him to meet me downtown, if he has no other plans.

- Any particular place downtown?

- No, he knows where. Harvey knows this town like a book.

- But how will I recognize your friend?

- You can't miss him, Mrs. Chumley. He's a pooka.

- A pooka? Is that something new?

- No, no. As I understand it, that's something very old.

- But Harvey's not only a pooka, he's also my best friend.

- If Harvey's said to me once, I'll bet he's said, oh, probably a million times, he said, Mr. Dowd, I would do anything for you.

- How sweet.

- Yeah. He's also very fond of my sister Veta. But Veta doesn't seem to care for Harvey.

- Now don't you think that's rather too bad, Mrs. Chumley?
