From the beginning of the book until the end, Skeeter's attitudes completely change.
Having grown up in a southern family of means, the way of life she had always known was that every family had black maids. This was a way of life for her and also almost everyone she knew in Jackson, Mississippi.
As the book goes on, and Skeeter hears more and more of the maids' stories of what they've experienced working in white homes, her eyes become opened to the injustices that the maids were subjected to.
Her eyes also become opened to the mistreatment of the maids by people who have been her friends for her entire life.
Her own immediate family had driven away Constantine, the maid who had practically raised her.
By the time her interviews of the maids are finished, and her book containing the interviews is published, Skeeter has totally changed her thinking and attitudes towards black people from what she had known throughout her entire childhood.
