" what we love is too much in the past, consists too much in the time that we have spent together for us to require the whole woman; we wish only to be sure that it is she, not to be mistaken as to her identity, a thing far more important than beauty to those who are in love; her cheeks may grow hollow, her body thin, even to those who were originally most proud, in the eyes of the world, of their domination over beauty, that little tip of a nose, that sign in which is summed up the permanent personality of a woman, that algebraical formula, that constant, is sufficient to prevent a man who is courted in the highest society and is in love with her from being free upon a single evening because he is spending his evenings in brushing and entangling, until it is time to go to bed, the hair of the woman whom he loves, or simply in staying by her side, so that he may be with her or she with him, or merely that she may not be with other people.
