Every time I get complacent and start to really enjoy the book, Scarlett thinks something like this:
The negroes she passed turned insolent grins at her and laughed among themselves as she hurried by, slipping and sliding in the mud, stopping, panting to replace her slippers. How dared they laugh, the black apes! How dared they grin at her, Scarlett O'Hara of Tara! She'd like to have them all whipped until the blood ran down their backs. What devils the Yankees were to set them free, free to jeer at white people!
(I've been making this face a lot.)
