Read this passage from Eudora Welty's "A Visit of Charity": There was loose, bulging linoleum on the floor. Marian felt as if she were walking on the waves, but the nurse paid no attention to it. There was a smell in the hall like the interior of a clock. Everything was silent until, behind one of the doors, an old lady of some kind cleared her throat like a sheep bleating. This decided the nurse. Stopping in her tracks, she first extended her arm, bent her elbow, and leaned forward from the hips—all to examine the watch strapped to her wrist; then she gave a loud double-rap on the door. "There are two in each room," the nurse remarked over her shoulder. "Two what?" asked Marian without thinking. The sound like a sheep's bleating almost made her turn around and run back.
