Scout’s teacher, miss caroline, gets mad at scout because she

Scout's teacher, Miss Caroline, gets mad at Scout because unlike the rest of her classmates, she knows how to read and write! Miss Caroline dislikes this because she is from a totally different town, so she knows nobody! She also wants everyone to treat her as the teacher, she wants complete control of the classroom, and she wants to be the only person to teach. She tells Scout not to let her father teach her again, but Scout pays no mind to her.
