This young man is strutting up the street with his boom box. He’s a big guy with a shaved head, sporting new sneakers and a parka. Suddenly he stops, looks behind him at ground level and gives a c’mon jerk of his head. Out of the crowd hurries a tiny Chihuahua. The dog rushes to the young man’s side and then sits nervously at his feet. The man pauses a moment, then resumes strutting.
