Once he begins it, Jonas's training makes clear his uniqueness, for the Receiver of Memory is just that—a person who bears the burden of the memories from all of history, and who is the only one allowed access to books beyond schoolbooks and the rulebook issued to every household. The current Receiver, who asks Jonas to call him the Giver, begins the process of transferring those memories to Jonas, for the ordinary person in the Community knows nothing of the past. These memories, and being the only Community member allowed access to books about the past, give the Receiver perspective to advise the Council of Elders. The first memory is of sliding down a snow-covered hill on a sled, pleasantness made shocking by the fact that Jonas has never seen a sled, or snow, or a hill—for the memories of even these things has been given up to assure security and conformity (called Sameness). Even color has been surrendered, and the Giver shows Jonas a rainbow. Less pleasantly, he gives Jonas memories of hunger and war, things alien to the boy. Hanging over Jonas's training is the fact that the Giver once before had an apprentice, named Rosemary, but the boy finds his parents and the Giver reluctant to discuss what happened to her.
