Jonas's first taste of real pain in the novel The Giver by Lois Lowry is when he receives the memory of war. This memory, given to him by the Giver, is described as a deeply unsettling and painful experience. It is a stark contrast to the peaceful and controlled life in the community, showing Jonas the harsh realities of the world beyond.
The memory is so powerful that it causes Jonas to experience physical pain, including a burning sensation in his chest and a feeling of nausea. This is a significant moment in the novel as it marks Jonas's transition from a naive and sheltered child to someone who understands the complexities of human emotions and the true cost of peace.
The memory of war also serves as a catalyst for Jonas's decision to leave the community and seek a better future. He recognizes the importance of individuality, choice, and the right to feel pain as part of the human experience.
