How is Scout stubborn in the beginning of the book?

In To Kill A Mockingbird, the novel's narrator and main protagonist Scout acts as an important female character in the literary canon due to her stubbornness and strong-willed attitude. She frequently gets into disagreements with Calpurnia and becomes frustrated or angry when Calpurnia does not see her side of the argument.
She gets into trouble early on in the novel when she speaks poorly of one of the more unfortunate students in her class. When she is scolded by her teacher, she takes out her frustration and anger on another child during recess. This shows her difficulty in being able to see how or why she was wrong.
Scout is also stubborn in her refusal to act traditionally feminine. While other girls her age wear dresses and play with dolls, she wears overalls and plays outside with her brother and their friend Dill. By refusing to understand why she should act differently for any other reason, it becomes clear that she is a stubborn girl. Of course, the stubbornness evidenced by Scout's actions is not an entirely negative trait; it makes her a strong-willed and independent character who does not conform or submit to immorality.
