Oliver has stated many times his dislike of hearing advice from his younger sister, so it is his own fault if he has not got sense enough to see which way the wind is blowing.
In Patricia C. Wrede's "Sorcery & Cecelia: or The Enchanted Chocolate Pot," Oliver consistently expresses his frustration with unsolicited advice from his younger sister. His dismissal of her insights reflects a lack of awareness regarding the changing circumstances they face, which could ultimately lead to negative consequences. This suggests that his resistance to listening to her may hinder his ability to navigate their enchanted world effectively.
Oliver's predicament serves as a reminder that disregarding the perspectives of others, especially those close to us, can lead to misunderstandings and missed opportunities. The dynamic between him and his sister illustrates the importance of open-mindedness, particularly in tumultuous situations where wisdom can come from unexpected sources.
