"Oh, I did," I piped readily. "The way I see it – here, let me take them books for you, Miz Lillian Jean – the way I see it, we all gotta do what we gotta do. And that's what I'm gonna do from now on. Just what I gotta."

How does this scene motivate Cassie?

It makes her angry that Lillian Jean thinks she is apologizing.
It makes her astonished about Lillian Jean’s behavior in Strawberry.
It makes her sad that she and Lillian Jean cannot be friends.
