Chapter Four, The Boy In The Striped Pajamas. In chapter four of the book, Bruno and Gretel continue to peer over the window and observe the children and adults on the other side of the fence, all wearing striped pajamas. Gretel comes to the conclusion that she doesn't want to play with them, because they look like they've never bathed before. Bruno however, decides it is best to not judge them, as you can never and should never judge a book by its cover. As Gretel keeps peering out of the window, an uncomfortable atmosphere arises, one of fear. Gretel becomes scared, once again showing that she has not fully matured. Although gretel doesn't directly show her fear, you can infer she is uncomfortable and unsire of the future. Bruno too realizes this and wants to seek comfort from his sister, but realizes that his sister too is unsure of the situation. This is a point in the story in which you can realize that both Bruno and Gretel realize the enormity of the situation.
During this chapter, I felt a little scared. The way that the people on the other side of the fence are described gives you a sense of fear, not a type of scary movie fear, but actual fear. This is when I also felt a little sad for Bruno, because he is pretty much alone, no one can comfort him, not his father, mother or sister.

In chapter three of "The Boy In The Stripped Pajamas" Bruno goes to speak to his sister and he shows how much of a snob his sister really is. He admits to be a little scared of his sister and her "monster" friends. Talking to her is when he realizes that he will stay at "out-with" or Auschwitz longer than he expected. He mentions to his sister about the children in the other side of the fence and that is when he realizes that she isn't as mature as he thought she was, as she was a little apprehensive when she went to look over to where the children were.
During this chapter I felt a little nervous, as the author begins to hint that there is something that is not right. With previous knowledge, I knew that it was the concentration camp and that those children were Jewish. I felt a little nervous and saddened  by this horrible part of world history
