Write a summary of Chapter 1 of the novel The Boy in the Striped Pajamas.

At the beginning of Chapter 1, Bruno, a nine-year-old boy living in Berlin, comes home to find his family's maid, Maria, packing up all of his belongings. Bruno's mother then walks into his room and explains why Maria is packing his things. He follows his mother downstairs where she tells him that they are moving because his father's job has forced them to relocate. Bruno then begins to think about what his father does for a living and realizes that he doesn't really know what he does. Bruno then thinks about his friends and how much he will miss them. Bruno is upset about the news and slides down the long banister as he reminisces about his house. He mentions that he will miss the banister as well as living close to his grandparents. Bruno then overhears his mother and father arguing in his father's office. Dejected, Bruno walks into his room to help Maria pack his things.
