Quote context

[...]

- Hello, Wilma.

- Good afternoon, Mr. Parrish.

- Have you seen Homer?

- He's out in the woodshed. Says he wants to get in some practice shooting. So he can go hunting. Thought that he'd seen enough shooting in the war.

- Well, I guess he just wants to find something to occupy himself with.

- I guess so.

- I wish there was something I knew to do for him. His mother and I have tried to make him feel at home. But he just keeps to himself all the time.

- Hello, Luella. What are you kids doing?

- Oh, nothing, we're just playing.

- That's his girl. They're engaged.

- Oh, hello, Wilma.

- Hello.

- Looking for something?

- No. Go right ahead.

- How'd you do, Homer?

- Only fair.

- Well, you did fine.

- I'll do better.

- I've been wanting to have a chance to talk to you.

- What about?

- About everything.

- About us.

- What about us? We're all right, aren't we?

- No.
