FAREWELL! thou art too dear for my possessing, <br />And like enough thou know'st thy estimate: <br />The charter of thy worth gives thee releasing; <br />My bonds in thee are all determinate. <br />For how do I hold thee but by thy granting? <br />And for that riches where is my deserving? <br />The cause of this fair gift in me is wanting, <br />And so my patent back again is swerving. <br />Thyself thou gav'st, thy own worth then not knowing, <br />Or me, to whom thou gav'st it, else mistaking; <br />So thy great gift, upon misprision growing, <br />Comes home again, on better judgment making. <br /> Thus have I had thee, as a dream doth flatter <br /> In sleep a King; but waking, no such matter.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnets-ix/
