What does Mrs. Pettifogger need to understand about Hubert's difficulties, according to the teacher?

Mrs. Pettifogger needs to focus on Hubert's understanding of reality because it is crucial to grasp the nature of the challenges he faces. This aspect encompasses not only what Hubert perceives but also how he interprets and interacts with the world around him. If his understanding of reality is skewed or limited, it could significantly impact his ability to engage in social interactions, perform academically, or utilize his creativity effectively.
