SPOILER ALERT.
There is a little girl in the story named Sophie. Sophie appears to be “normal” although when she gets her foot stuck in between two boulders, her biggest secret is visually told. The secret is that Sophie has six toes on her foot instead of 5. I’d say David is surprised by this simply because it isn’t something you see every day. David is the only other person (except for Sophie’s parents) who knows this secret being held. His father also overheard David talking how he wishes he had another arm so he could complete a task more easily. His father got very upset, and said if that happened David would be a disgrace. Therefore, David’s father called Sophie a disgrace. ...Sara
