Read the excerpt from Flannery O'Connor's "The life you save may be your own" Mr. Shiftlet was so shocked that for about a hundred feet he drove along slowly with the door stiff open. A cloud, the exact color of the boy"s hat and shaped like a turnip, had descended over the sun, and another, worse looking, crouched behind the car. Mr. Shiftlet felt that the rottenness of the world was about to engulf him. He raised his arm and let it fall again to his breast. "Oh Lord!" he prayed. "Break forth and wash the slime from the earth!" The turnip continued slowly to descend. After a few minutes the was a guffawing peal of thunder from behind and fantastic raindrop, like tin-can, crashed over the rear of Mr. Shiftlet's car.
