At the beginning of the story, Lizbeth is very childlike. For example, "We children made a game of thinking of ways to disturb John Burke and then to elude his violent retribution. But out real fun and our real fear lay in Miss Lottie herself." The story states many ways Lizbeth and Joey would mess with John Burke and Miss Lottie, which shows they're childlike character.
Throughout the story, Lizbeth's character develops and becomes less childlike. For example, "I did not join the merriment when the kids gathered again under the oak in our bare yard. Suddenly, I was ashamed, and I did not like being ashamed. The child in me sulked and said it was all fun, but the woman in me flinched at the thought of the malicious attack that I had led."
At the end of the story, Lizabeth's character is adult-like. For example, "I scrambled to my feet and just stood there and stared at her, and that was the moment when childhood faded and womanhood began. That violent, crazy act was the last act of childhood. For as I gazed at the immobile face with sad, weary eyes. I gazed upon a reality that is hidden to childhood."
