Atticus. From her father, Scout learns about tolerance toward others and how it is best to "climb into his skin and walk around in it" first. She learns about humility and how Atticus has never bragged about his marksmanship skills since "People in their right minds never take pride in their talents." He teaches her that education is important, reading to her every night and convincing her to return to school after her bad first day in the first grade. She learns from him that bravery is not necessarily "a man with a gun in his hand," and why it is a "sin to kill a mockingbird."
Miss Caroline. Scout learns that being well-educated doesn't always translate into teaching skills. She discovers that teachers can be rude and unfair and, in Miss Caroline's case, downright ignorant when she suggests that she must "undo the damage" done by Scout learning to read at such an early age.
Aunt Alexandra. Scout learns all about Aunt Alexandra's obsession with heredity and the Finch family's "gentle breeding," but like Atticus, she doesn't really buy into her aunt's beliefs. She disagrees with Alexandra's definition of "Fine Folks," and comes to believe that the only reason she has come to live in Maycomb is "to help us choose our friends." But Alexandra finally begins to lighten up a bit toward the end of the novel: Scout recognizes Alexandra's true ladylike virtues at the Missionary Circle tea--"After all, if Aunty could be a lady at a time like this, so could I"--and her motherly instincts following the attack by Bob Ewell when her aunt calls her "darling" and "brought me my overalls... the garments she most despised."
