As a young girl, Lizabeth revels in her "chaotic childhood emotions" and later uses them to justify her actions. She leads an assault on Miss Lottie's with no afterthought. Lizabeth does not realize the severity of the situation she lives in. She sees Miss Lottie's marigolds as a detriment to the "perfect ugliness" of the older lady's house.
In her transition, Lizabeth is being exposed the adult's view of what is happening around her. With this new view of the world around her, yet not the maturity to cope with it, she feels confused as a flood of new emotions begin to flow over her. So, she bottles up the emotions she cannot cope with and later releases them in destroying the marigolds.
Having destroyed the Marigolds, Lizabeth is no longer struggling to cope with the reality of her dismal situation. She completes her transition to adulthood and no longer makes the decisions she now regrets, as an adult. Lizabeth understands what is happening around her with new eyes to see it. This, as she comes to learn, is adulthood
