How did Aunt Polly come to know about the glad game?

Aunt Polly learned about the glad game through her niece, Pollyanna Whittier, who introduced it as a way to find something to be glad about in every situation. Pollyanna had developed this optimistic outlook from her father, who taught her to focus on the positive, even in adversity. As she shared her experiences and the game's principles with Aunt Polly, the older woman began to see its value and how it could transform her own perspective on life. This newfound awareness helped Aunt Polly to embrace a more positive attitude, influenced by Pollyanna's unwavering optimism.
