What metaphors are used in The Difference by Ellen Glasgow?

As Margaret dresses to confront her husband's mistress, she makes a metaphor of the "veil" she wears, as "she reflected, with bitter mirth, that only in novels could one hide one's identity behind a veil." Margaret continues to hide her inner identity, however, behind the veil of her impeccable manners and mask-like facial expressions. Even when she confronts Rose, she hides her true feelings behind her gracious manners: "and though she tried to make her voice insolent, the deep instinct of good manners was greater than her effort."
