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
