- We must stop this war.

- Too late, Nathan. Young men do not listen to me.

- They listen to big medicine. Yellow hair. Custer dead.

- Buffalo come back, great sign. Too late, Nathan.

- You will come with me. Hunt buffalo together. Smoke many pipes.

- We are too old for war.

- Yes, we are too old for war, but old men should stop wars.

- Too late, too late. Many squaws will sing the death songs. Many lodges will be empty.

- You come with me. We hunt buffalo, get drunk together. Hallelujah, hallelujah!

- No, old friend, I must go. I go far away.

- Then, Nathan, my brother, go in peace.
