When said, “we don’t have the luxury of thinking” told by Mother, this means that Mother, Bruno, and Gretel all aren’t allowed to make their own decisions, so some people, Father, made all the decisions for them. Mother, Gretel, and Bruno (mostly Bruno) didn’t want to move to this new house outside of Berlin but they had no choice, they were practically “forced” to move to Poland. Mother and Father probably should’ve talked about leaving and moving to this different house in Poland but Father didn’t want to say no to the Fury, Hitler. So Father went ahead and didn’t ask Mother, Bruno, and Gretel what they thought (“we don’t have the luxury to think”).
This statement that has been made reflects to the theme of obedience and conformity because Mother, Father, Bruno, and Gretel all had to change and start living in their new house in Poland and change with all the ways their family is changing. Like how Father is now to be called Commandant. And also Mother, Bruno, and Gretel had to obey Father and they all had to obey Hitler’s orders to move because Father was a soldier for the Nazi’s and Hitler wanted him to move closer to the concentration camps, probably so it was easier for Father to get there quicker. Some examples supporting my statement would include: “When they first saw their new house Bruno’s eyes opened wide, his mouth made the shape of an O and his arms stretched out at his sides once again. Everything about it seemed to be the exact opposite of their old home and he couldn’t believe that they were really going to live there.” Another example includes: ” ‘But what about school?’ said Bruno, interrupting her, a thing he knew he was not supposed to do but which he felt he would be forgiven for on this occasion.”
