After talking to Maria, how has Bruno's opinion of her changed?

In Chapter 6, Bruno approaches Maria and asks her if she hates living at Out-With as much as he does. Maria does not answer his question and talks about the old house when he asks her if she likes Out-With again. Bruno calls his father stupid, and Maria looks horrified. She tells him that he must never say that about his father again because he is a good man. Maria explains how Bruno's father gave her a job and took care of her mother's funeral. As Maria is explaining to Bruno her life story and background, Bruno begins to gain perspective into who Maria is as a person. He begins to see her as a person with a history and not just the family maid. Maria mentions that Bruno's father has a kind soul, and wonders how he could give orders to slaughter innocent Jewish people on an everyday basis. She keeps her thoughts to herself and tells Bruno it is best if he does not verbalize his feelings.
