Final answer:
Greg's perception of his father evolves from seeing him as overly strict to understanding and appreciating his care and guidance. This change occurs after Greg meets Lemon Brown and learns about the true value of treasures, which are not always material but often sentimental.
Step-by-step explanation:
In the story "The Treasure of Lemon Brown" by Walter Dean Myers, Greg starts with feelings of resentment toward his father for his restrictions and lack of understanding about his interests, particularly basketball. At the beginning of the story, Greg feels his father is too strict and does not take Greg’s desires into account, leading to tension at home. By the end of the story, after meeting Lemon Brown and learning about his treasure, which consists of old newspaper clippings and a harmonica, Greg's perspective shifts. He comes to understand the significance of intangible legacies and the importance of family. He realizes that his father's involvement and strictness are forms of caring and guidance, not just constraints on his freedom.
Lemon Brown helped Greg to see that treasures don't have to be valuable in a monetary sense; they can be precious because of their sentimental value and the stories and memories they carry. This newfound understanding makes Greg appreciate his father's lessons and expectations, recognizing they are part of what his father considers his “treasure” to pass on to Greg.
