[...] It was impossible, I said in response to his question, to give the reasons why the marriage had ended: among other things a marriage is a system of belief, a story, and though it manifests itself in things that are real enough, the impulse that drives it is ultimately mysterious. What was real, in the end, was the loss of the house, which had become the geographical location for things that had gone absent and which represented, I supposed, the hope that they might one day return. To move from the house was to declare, in a way, that we had stopped waiting; we could no longer be found at the usual number, the usual address. My younger son, I told him, has the very annoying habit of immediately leaving the place where you have agreed to meet him, if you aren’t there when he arrives. Instead he goes in search of you, and becomes frustrated and lost. I couldn’t find you! he cries afterwards, invariably aggrieved. But the only hope of finding anything is to stay exactly where you are, at the agreed place. It’s just a question of how long you can hold out.
