The wall

1. It is ironic because the boy is playing with a plane, his father died because a plane and the whole country is suffering because bombardings. 
2. We can infer that the boys sees himself with this clothes of his dad that died at war, representing what war left to him and that he grew up without a paternal figure, and he in the future probably will do the same with his son.
3. It makes a relationship between the kids and and animals, showing that the kids are nobody only something that will be taken to the slaughterhouse. 
4. I believe that this scene represents an idea of hope, because he can see himself with the other students making a revolution against the education system. 
5.in my opinion it portrays an strict and conservative education that dont allow the children to think different of what the schools wants.
6. war and loneliness are portrayed with the use of death and blood that were a consequence of the war, what it left.
