[...]

- Don't you just love it?

- Love what?

- Tiffany's.

- Isn't it wonderful? You see what I mean how nothing bad could ever happen to you in a place like this?

- It isn't that I give a hoot about jewellery, except diamonds, of course. Like that.

- What do you think?

- Well...

- Of course, personally, I think it would be tacky to wear diamonds before I'm 40.

- Well, you're right. But in the meantime, you should have something.

- I'll wait.

- No. I'm gonna buy you a present. You bought me one, a typewriter ribbon, and it brought me luck.

- All right, but Tiffany's can be pretty expensive.
