Classic Poem

LOVE not me for comely grace,
For my pleasing eye or face,
Nor for any outward part,
No, nor for a constant heart:
   For these may fail or turn to ill,
   So thou and I shall sever:
Keep, therefore, a true woman's eye,
And love me still but know not why--
   So hast thou the same reason still
   To doat upon me ever!
