At the beginning of the story, Winnie was bored, restless, and feeling trapped in her own yard. She longed to go outside the gates of her family's home, but she knew she was not permitted. Winnie was a well-behaved young lady who played by her family's rules. As her intrigue of the Man in the Yellow Suit and the music from the woods grows, she gives in to an adolescent impulse to go exploring. After all, the woods belonged to her family. Once "kidnapped" by the Tucks, her fear grew into interest and affection for the peculiar family. All the attention they lavished upon her was a great difference from how her own family treated her. The Tucks were open and loving, whereas her family was proper and closed-mouthed about "adult" topics of interest. As Winnie grows to love the Tucks, she becomes very protective of them. She returns home to avoid any further trouble for the Tucks. She becomes adventuresome when she joins Jessie and Miles in breaking Mae out of jail and brave when she takes Mae's place. When the question comes down to whether or not she will drink the spring water and live with Jessie forever, her maturity level has grown. She realizes all in life she will miss and chooses a mortal life.
