Our fortieth anniversary celebrated a marriage that had survived 429 tubes of toothpaste squeezed from the wrong end, three children and three sets of braces, five dogs and four homes, 2,583 arguments and just that many reconciliations, one bout of prostate cancer, one near conversion to Judaism, one near divorce, a few months of perfect hate, and forty years of love. We celebrated our forty years of marriage with a three-week trip to South America.
