A man walks alone in the park and beside him a woman walks, also alone. How does one know? It is as though a line exists between them, like a line on a playing field. And yet, in a photograph they might appear a married couple, weary of each other and of the many winters they have endured together. At another time, they might be strangers about to meet by accident. She drops her book; stooping to pick it up, she touches, by accident, his hand and her heart springs open like a child’s music box. And out of the box comes a little ballerina made of wood. I have created this, the man thinks; though she can only whirl in place, still she is a dancer of some kind, not simply a block of wood. This must explain the puzzling music coming from the trees.
