Sonnet 116

This is a big Shakespeare anniversary year, so let me get in early. This isn't one of the sonnets that he dedicated to his mysterious 'Dark Lady', but if any other dark lady is reading she can assume it's for her.

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