Greg could see him clearly. He was an old man. His black, heavily wrinkled face was surrounded by a halo of crinkly white hair and whiskers that seemed to separate his head from the layers of dirty coats piled on his smallish frame. His pants were bagged to the knee, where they were met with rags that went down to the old shoes. . . .

“What are you doing here?” Greg asked.

“This is where I’m staying,” Lemon Brown said. “What you here for?”

“Told you it was raining out,” Greg said, leaning against the back of the couch until he felt it give slightly.

“Ain’t you got no home?”

“I got a home,” Greg answered.
