- What I tell you!

- Oh, Miss Doshy, Sally wants Johnny to stay here for awhile with you.

- What will you do?

- Oh, I'm going back. And I want Sally to go with me.

- It's no use, John. I'm not going back.

- Then I'll have to go without you.

- And I'd better hurry, or I'll miss my train.

- Miss it! You won't regret it.

- Daddy? You're going back?

- Yes, son.

- Why?

- I have to.

- But... You... You've never left Mama and me before.

- No, I know. But I've got a job to do, and you've got one too. Taking care of Mother and Grandmother. You'll do that now for me, won't you? Goodbye, son.
