In The Boy in The Striped Pajamas, Bruno is an inquisitive boy, not at all impressed with his parents' decision to move out of Berlin to "Out-With". He can see out of his window what to him looks "desolate" and which Gretel, his sister, first thinks may be the countryside but, after consideration, they both decide that it is definitely not the countryside. Bruno and Gretel can see the people in the camp on the other side of a fence and, although it makes no sense, Gretel imagines they may be actors, busy with a rehearsal. Bruno is particularly interested in the fact that there are children - definitely scope for some friends. Gretel, however, is not impressed with the appearance of these children and thinks they are definitely not her "type."
Bruno persists in his interest and manages to gather enough courage to approach his father. His father's response foreshadows what will follow but Bruno, the innocent and ever obedient son, does not question his father, or the meaning of his father's words, although his answer is not what Bruno was looking for :
They’re not people at all...at least not as we understand the term....You have nothing
whatsoever in common with them.
