she was now walking with some children (students?) on the surface of a lake. Everywhere each of them stepped there appeared a five-sided crack, all of these beautifully even, so that the ice became like a tiled floor. The children asked her the name of these ice tiles, and she answered with confidence, iambic pentameter. But they laughed and with this laughter the cracks widened. She realized her mistake then and knew that only the right word would save the situation, but she could not grasp it.
