Read this passage from Eudora Welty's "A Visit of Charity":
Marian stood enclosed by a bed, a washstand and a chair; the tiny room had altogether too much furniture. Everything smelled wet—even the bare floor. She held on to the back of the chair, which was wicker and felt soft and damp. Her heart beat more and more slowly, her hands got colder and colder, and she could not hear whether the old women were saying anything or not. She could not see them very clearly. How dark it was! The window shade was down, and the only door was shut. Marian looked at the ceiling. . . . It was like being caught in a robbers' cave, just before one was murdered. "Did you come to be our little girl for a while?" the first robber asked. Then something was snatched from Marian's hand—the little potted plant.
