Where does gretel think they are explain your answer in the boy in the striped pajamas?

In "The Boy in the Striped Pajamas," Gretel initially believes they are moving to a house in the countryside, as their father has been promoted to commandant of a concentration camp. She is naive and unaware of the true nature of their new surroundings, often referring to it as "Out-With" instead of Auschwitz. Her understanding is limited by her youth and the Propaganda surrounding them, which obscures the reality of the situation. This reflects her innocence and the broader theme of the book regarding the loss of childhood in the face of war.
