A figurative use of “sidelong” by Virginia Woolf
“The man looks the world full in the face, as if it were made for his uses and fashioned to his liking. The woman takes a sidelong glance at it, full of subtlety, even of suspicion. Had they both worn the same clothes, it is possible that their outlook might have been the same.” (Virginia Woolf)
