A tiny little boy dawdles behind his mother on the walkway. Skinny legs and sleeves too long. His mother waits, and he hands her a drink to carry. Further along he finds a metal plate set into the path and stops to examine it. He goes down on all fours, then rocks back into a squat and watches his mother, waiting for her to notice. She does, and she calls to him. He crab-walks to the other side of the metal plate and sits down comfortably with his back to her.
