There's a scene where Jeffrey is frustrated with their overprotective and controlling behavior. He feels like they're constantly trying to "fix" him and make him conform to their expectations. This is particularly evident when they sign him up for the musical school, hoping it will help him "become a normal boy."
However, Jeffrey doesn't scream at them during this scene. Instead, he expresses his frustration in other ways, such as:
* Running away: This is his usual way of dealing with situations he finds unbearable.
* Refusing to participate: He actively avoids participating in the musical school, which angers Aunt Dot and Uncle Dan.
* Giving them the silent treatment: He mostly ignores their attempts to engage him.
Jeffrey's frustration with Aunt Dot and Uncle Dan stems from his desire to be his own person and live his life on his own terms. He doesn't want to be controlled or "fixed," and he's deeply unhappy with their constant attempts to change him. This conflict is a central theme in the story, highlighting the importance of individuality and the right to be different.
