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.
