1 | Let me not to the marriage of true minds
2 | Admit impediments; love is not love
3 | Which alters when it alteration finds,
4 | Or bends with the remover to remove.
5 | Oh, no, it is an ever fixed mark
6 | That looks on tempests and is never shaken;
7 | It is the star to every wand'ring bark,
8 | Whose worth's unknown, although his height be taken.
9 | Love's not Time's fool, though rosy lips and cheeks
10 | Within his bending sickle's compass come;
11 | Love alters not with his brief hours and weeks,
12 | But bears it out even to the edge of Doom.
13 | If this be error and upon me proved,
14 | I never writ, nor no man ever loved.
