When does the narrator change point of views in the story?
As you know, Scout is the narrator of the story. She is a little girl. At the outset of the book she is 6 and by the end she is 9. However, she is reflecting about her youth as an older woman.
From this perspective, we can say that Scout does change her point of view several times. Another way to put it is she matures throughout the novel. In light of this, let me give you a few examples.
First, at the outset of the novel, all the children, Scout included, viewed Boo Radley as a monster. However, as the novel progresses, Scout realizes that Boo is a kind soul, and eventually they become friends.
Second, Scout, as a young child, had a very innocent view of the world. All was well in Maycomb. When the trial of Tom Robinson occurred, she began to realize the ugliness in people's hearts. She also realized this when Bob Ewell almost killed her.
Finally, she also changed her opinion of Atticus. At first, he was a mediocre dad in every respect, but by the end of the novel she realized that Atticus was a very honorable man.
