In The Giver, the community is totally socially conditioned and controlled, right down to sexual impulses. Teachers are valued for their reinforcement of social conditioning and social acceptable behavior. In chapter three, Jonas--on a lark--grabs an apple from a snack table and tosses it to his friend, Asher, beginning a simple game of catch. However, this act breaks the rules and is acknowledged publicly over the community's loud speaker later that day. In essence, Jonas is chastised without being mentioned by name.
"Attention, this is a reminder to male elevens that objects are not to be removed from the recreation area and that snacks are to be eaten, not hoarded..." (23)
Jonas responds by discarding the apple and making an apology to the Recreation Director. Children in the community are required to apologize to teachers for any misdeeds.
The apple event is integral to the story because it is the first time Jonas shows himself as being different, even though he doesn't realize it. As he throws the apple, he noticed its color flash. We later discover he has seen the color red for the first time. All others in the community, except the Giver, see ony in black and white.
