What are some examples of dramatic irony when Bruno meets Shmuel in The Boy In the Striped Pajamas by John Boyne?

Dramatic irony is found in a novel when the reader knows something that a character does not know.  In this case, there are many examples of dramatic irony found in The Boy in the Striped Pajamas and especially in reference to the character of nine-year-old Bruno when he meets Shmuel. First, Bruno notices something that gives the book its title:  the boy on the other side of the fence is wearing “striped pajamas.”  This is dramatic irony because the reader knows that these are not “striped pajamas,” but the uniform given to concentration camp prisoners.  Next, Bruno makes the assumption that all of these people are working on some kind of “farm.”  This is dramatic irony because the reader knows this is not a “farm,” but the Auschwitz concentration camp where people are held and overworked against their will.  A final interesting thing to note about the first meeting of Bruno and Shmuel is Shmuel’s condition:  bare feet, pale skin, dirty clothes, and sad eyes.  This is dramatic irony because the reader knows Shmuel’s condition is not due to chosen farm work, but instead from the horrid conditions within the Nazi death camp.
