The way the book is written there are gaps all over the place that you are expected to fill in. For some reason this reminds me a bit of the Secret Diary of Adrian Mole but it has been years since I read that so I might be wrong.
Although the style is akin to the Mole Diary the content is nowhere near it as Bruno makes a friend across the other side of the wire and starts to get a slight understanding of the treatment that some of the Jews are being given by the Germans around them.
But he is still light years away from understanding everything around him and his innocence, often portrayed as arrogance in his replies to others, reveals his lack of knowledge.
In some respects he is a victim but of course nowhere near those on the other side of the wire and the purpose of telling the story through the eyes of a child is clearly not just to appeal to a younger readership but also to unfold the concentration camp world in a much more innocent and simple way.
Last chunk tomorrow…
