A few days after the new lessons began, Bruno sat alone in his room and recalled how he’d spent his childhood exploring his family’s massive house. He decided to try exploring again, though he’d have to do it outside since the new house was too small. Bruno thought about the people in the striped pajamas outside his window, and he realized that in the months his family had been at Out-With, he hadn’t wondered much about who they were or what they were doing there. He asked himself if those people were really all that different from the people on his side of the fence.
