If thou must love me, let it be for nought Except for love's sake only. Do not say, I love her for her smile . . . her look . . . her way Of speaking gently . . . for a trick of thought That falls in well with mine, and, certes, brought A sense of pleasant ease on such a day- For these things in themselves, Beloved, may be changed, or change for thee- and love so wrought, May be unwrought so.

Elizabeth Barrett Browning
