I looked around and up at Mr. Cunningham, whose face was equally impassive. Then he did a peculiar thing. He squatted down and took me by both shoulders.
“I’ll tell him you said hey, little lady,” he said.
Then he straightened up and waved a big paw. “Let’s clear out,” he called. “Let’s get going, boys.”

To Kill a Mockingbird, Chapter 15. Walter Cunningham calls off the mob that is intent on lynching Tom Robinson, when Scout cleverly and courageously engages in small talk about Cunningham’s son being a good boy – “Maybe he told you about me, I beat him up one time but he was real nice about it. Tell him hey for me, won’t you?” Scout saves Tom Robinson’s life by this.
