LET me not to the marriage of true minds <br />Admit impediments. Love is not love <br />Which alters when it alteration finds, <br />Or bends with the remover to remove: <br />O, no! it is an ever-fixed mark, <br />That looks on tempests and is never shaken; <br />It is the star to every wand'ring bark, <br />Whose worth 's unknown, although his height be taken. <br />Love 's not Time's fool, though rosy lips and cheeks <br />Within his bending sickle's compass come; <br />Love alters not with his brief hours and weeks, <br />But bears it out even to the edge of doom:-- <br /> If this be error and upon me proved, <br /> I never writ, nor no man ever loved.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnets-xviii/
