At noon that day, Winnie sits on the closely cropped grass inside her fence, talking to a toad outside. She tells it that she might run away tomorrow, but she can't tell if the toad is listening or not. Winnie's been at the fence for a while. She came out earlier feeling annoyed and angry, so she threw some pebbles in the toad's general direction. When she ran out of pebbles, she started to talk to it. Now, Winnie tells the toad she can't stand it much longer. As she does, a window in the cottage opens and Granny tells Winnie to not sit on the grass, while Winnie's mother calls her for lunch.
Though minor characters in the grand scheme of the novel, Winnie's mother and Granny show the reader here that they're likely overbearing--or at the very least, Winnie thinks they are. Winnie's desire for independence suggests that she's beginning to come of age and is getting ready to step out on her own, while her willingness to talk to the toad indicates that she's in need of a friend to connect with.
Winnie tells the toad that because she's an only child, the adults want to look at her and look after her all the time--but she just wants to be alone for a while. She says that she'd like to do something interesting that would make a difference, and she might like a new name too. Winnie suggests that she could keep a toad as a pet, but when the toad heaves itself further away from her, she suggests that her pet toad would be no better off than she is, as she's basically in a cage too. She laments that her family never lets her leave the yard by herself and declares that she's going to run away. Winnie's mother calls again and the toad begins to hop toward the wood. Winnie tells the toad she's serious about running away tomorrow.
By seeing the fenced yard as a cage, Winnie conceptualizes childhood as something that's being forced upon her. Notably, she sees the fence as something she can't just leave, just as she believes now that she can't just choose to not be a child anymore. Though this again speaks to Winnie's readiness to begin to come of age, her unwillingness to question her own agency or the efficacy of her boundaries shows that at this point, she still relies on and trusts the adults around her to mediate her experience with the outside world. Her mention of wanting to make a difference also introduces the idea that Winnie is starting to contemplate how to create a meaningful life.
