Examples of the themes in Boy In The Striped Pyjamas
Firstly, after spending a few months at Out-With without having anyone to play with, he meets Shumel who lives on the other side of the fence.He becomes really happy that he finally has a friend to talk to. Boyne is using the fence to show the difference between the unexpected friends and how the fence doesn't separate them from being friends. The fence symbolizes the chances that children have in that time of war when one is free and the other isn't.
When Bruno questions Maria about Pavel and his past, Maria's acted in a very nervous and scared manner by looking out the window, licking her lips and checking whether anyone was coming. it was obvious the Maria was scared, in fear. There were also many scenes where the theme of fear was involved
The theme of war is not represented in an obvious way, and examples of the theme of war are the way of how Bruno dies in the end by being gassed, the concentration camps itself, the army officers like Lieutenant Kotler and the Fury.
Morality is an underlying metaphor that flows through the story, like how his father is immoral because of his actions to wipe out the Jews. Payback is served at the end when father's son (Bruno) gets killed by something that was meant for the Jews, not the Germans. The same thing happens to Bruno when he ends up being killed by his own race, which was not the intention of the gas. This is called a cruel paradox. The moral of this story is whatever you do that is evil, you will be punished, in some way or another.There was no escape, same for the Jews in the camp.
