What changes after the Nazie arrive?
After looking out his bedroom window, Bruno wonders, "he watched hundreds of people in the distance ... [they] were wearing the same clothes as each other: a pair of grey striped pajamas" (Boyne 38).
As Bruno and Gretel look out the window, they see the people in the concentration camps; they are unaware of who the people are or why they are there. Bruno does note that everyone is wearing the same outfit; they appear universal. During the Holocaust, the Jews were stripped of their humanity in many ways. The forced conformity via the uniforms was only a small way the Nazis demoralized the victims. In addition, these uniforms portray the victims as "prisoners" or "criminals" making it seem like they have committed a crime.
