What is the exposition The Boy in the Striped Pajamas?

The exposition of "The Boy in the Striped Pajamas" introduces Bruno, an eight-year-old boy living in Nazi Germany during World War II. His family moves from Berlin to a house near a concentration camp, which Bruno initially perceives as a strange place. The story sets the stage for Bruno's innocence and curiOSity about the world around him, particularly his fascination with the "people in pajamas" he sees from his window, unaware of the true nature of the camp and the horrors it represents. This background establishes the contrast between Bruno's sheltered life and the grim reality of the Holocaust.
