Famous quotes containing the word twist:
“The hearts of small children are delicate organs. A cruel beginning in this world can twist them into curious shapes. The heart of a hurt child can shrink so that forever afterward it is hard and pitted as the seed of a peach. Or, again, the heart of such a child may fester and swell until it is misery to carry within the body, easily chafed and hurt by the most ordinary things.”
—Carson McCullers (1917–1967)
