Example from Literature
Marilla was a tall, thin woman, with angles and without curves; her dark hair showed some gray streaks and was always twisted up in a hard little knot behind with two wire hairpins stuck aggressively through it. She looked like a woman of narrow experience and rigid conscience, which she was; but there was a saving something about her mouth which, if it had been ever so slightly developed, might have been considered indicative of a sense of humor.— Lucy Maude Montgomery, Anne of Green Gables
