Quote context

- This letter, you wrote it, didn't you?

- Yes. That's a letter I wrote my wife. How'd you get it?

- Your wife is Japanese, and so any challenge to her, is a challenge to us, as well.

- It's between me and her.

- As from now on, she is no longer your wife.

- Huh? You... What was that?

- He's our top Kendo fighter. I hear you're good with a sword, too. Why don't you fight him?

- I don't want to.

- Well, you're not too bad, kid.

- Why don't you take my sword?

- You Chinese are rude.

- No, you're the ones who are rude.
