I squeezed her hand and said nothing. I knew little about Keats or his poetry, but I thought it possible that in his hopeless situation he would not have wanted to write precisely because he loved her so much. Lately I'd had the idea that Clarissa's interest in these hypothetical letters had something to do with our own situation, and with her conviction that love that did not find its expression in a letter was not perfect. In the months after we'd met, and before we'd bought the apartment, she had written me some beauties, passionately abstract in the ways our love was different from and superior to any that had ever existed. Perhaps that's the essence of a love letter, to celebrate the unique. I had tried to match her, but all that sincerity would permit me were the facts, and they seemed miraculous enough to me: a beautiful woman loved and wanted to be loved by a large, clumsy, balding fellow who could hardly believe his luck.
