What is the author's tone in White Teacher by Vivian Gussin Paley?

The tone of this novel is light. Mrs. Paley, as a kindergarten teacher, has taken on a subject that has a high potential for offense against one group of people or another. However, Mrs. Paley takes on this subject with honesty and the innocence that seems to be an important part of her job. Mrs. Paley makes no apologies to anyone, even when admitting her own inherent prejudice that has caused her to look at race in a way that separates her students into categories. Mrs. Paley does learn, however, to change her thinking and has written this book in hopes of helping other teachers learn from her experiences and treat race with the openness and honesty it deserves.
