Why does Julia not want her mother to make the story of the trout one of the evils of disobedience?

Julia does not want her mother to frame the story of the trout as one of the evils of disobedience because she believes it would unjustly cast her actions in a negative light. She recognizes that the story holds deeper significance and lessons beyond mere obedience. By avoiding this moralistic interpretation, Julia seeks to retain the complexity and nuance of her experiences rather than simplifying them into a cautionary tale. This reflects her desire for autonomy and a more profound understanding of her choices.
