Why does gretel hesitate before looking out of bruno’s window the boy in striped pajamas

Before Gretel looks out Bruno's window in Chapter 4, she hesitates. She is not sure that she wants to look out, because she is unsure she will like what she sees. Gretel is worried that she might see something that will frighten her or confuse her. When she finally looks out, she does not understand what she is looking at.
