How does Scout describe Calpurnia?

In chapter 1, Scout describes Calpurnia as a powerful force in her household. Calpurnia is the Finch's cook, but she is much more than a cook to the family. For example, Atticus relies on her to share the role of authority figure, while Jem and Scout rely on her for keeping order. Scout describes her relationship with Calpurnia in military terms: Calpurnia "was always ordering" Scout to leave the kitchen, their "battles were epic and one-sided," and Calpurnia consistently "won."
Scout describes Calpurnia as influential in other ways. In chapter 2, Scout remembers Calpurnia teaching her how to write, but "[i]n Calpurnia's teaching, there was no sentimentality." In chapter 3, Calpurnia teaches Scout important lessons about politeness and good manners when Walter is having lunch with them, and Scout recalls that "Atticus said Calpurnia had more education than most colored folks."
Though Scout often describes herself as resentful of Calpurnia, she also makes sure that the reader understands that Calpurnia always fulfills her responsibility to Atticus and to both Jem and Scout. Scout's descriptions might often sound negative, but Calpurnia's presence ultimately had a positive effect on Scout.
