She is nine, beloved, as open-faced as the sky and as self-contained. I have watched her grow. As recently as three or four years ago, she had a young child's perfectly shallow receptiveness; she fitted into the world of time, it fitted into her, as thoughtlessly as sky fits its edges, or a river its banks.

Now she is aware of some of the losses you incur by being here--the extortionary rent you have to pay as long as you stay.
