Jack is initially opposed to reaching out in this way; he recalls seeing Auggie for the first time in front of a Carvel ice cream shop, when he and August were only five or six. Jack was immediately afraid of August's face, and Veronica -- the babysitter for Jack and his little brother Jamie -- rushed the two boys away quickly and scolded them.
