Faulkner's Face in the Greek Mask

Faulkner uses the Greek mask to pull an emotion out of you as a reader. Every character that's introduced, even the minor characters have like some descriptions of their faces. For example, Charles Jr. when he comes back with his wife, the first time we're meeting this woman and Faulkner has a chance to make an impact here. And boy does he, he drops some serious racial slurs here.
