Walking towards the stream one day, I passed two little boys intent on their toy. It completely absorbed the attention of both the boy manipulating the device as well as his companion. It was the metal lid of a tin, perhaps a tin of powdered milk or ghee, with rounded edges, and a length of wire. The wire was bent at one end, to hook around the lid. The boy was driving the lid along the cement path with the wire. The path was not smooth and it took skill and concentration to keep the lid turning. The boy’s companion was as intent on the game as he was, perhaps he was waiting for his turn and mentally practising as he watched.
