Joe first walked by the man at 2 p.m. The man was standing in the middle of a busy sidewalk in Koreatown. He was bent over, face down. Joe could see only the top and back of the man's head. His hands were moving slowly near his knees. At about 3 p.m., Joe returned from his errands. The man was still on the sidewalk. He was in the same spot. Joe decided to stop. He stood nearby and watched the man. The man wasn't making a sound. He just stood there, bent over, face down. He seemed to be looking at his hands. His hands continued to move slowly in front of his knees. This man needs help, Joe thought. He felt sorry for the man. People continued to walk around the man. Joe went home. He told his wife about the man. "How did he get there?" she asked.
