Literary devices in The Boy in The Striped Pajamas

In the boy in the striped pajams it was mnot that easy to find literary devices because as its based on a true stroy

Symbolisim: i think that in the boy in thestriped pajamas the most symbolic and the object that most had a meaning was the " striped outfit" Bruno saw from the window when he arrived to Out-With. After when he discovered what was the really meaning of that " striped outfit"

Foreshadowing:
The most obvios for me clues that somwthing was going to happen was to Bruno, when bad things started to happen to him like him getting stuck in the swing and fighting with his parents and his sister greatel, like things like that and eventually something really bad happend to him.

Flashback:
What Bruno most remeberd and thought many times inthe story was of his old house, for example when he moved to Out-With his street was really like loonley and quite, so he rememberd of his old house in Berling in which he used to play with his friends and so.

Plot-twist:
I tuing that what changed everything for Bruno and his family, changing to With-Out. In Berlin Bruno had his friends, his grandparents, his wonderfull house, everything was perfect, until he moved to Out-With and tjings started turning other paths.

Atmosphere:
The atmosphere throught some oart of the book was like okay like not bad or good, but them it became a dark atmosphere a sad one a crying one, because of everything that happens, bad thing after bad things, so its really sad.
