Talking about Shakespeare always brings up this sonnet - the first bit of Bard I ever learned by heart.
Let me not to the marriage of true minds
Admit impediments. Love is not love
That alters when it alteration finds
Or bends with the remover to remove.
O, no! It is an ever-fixèd 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.
__________William Shakespeare
When trying to recite it, I usually stumble over the "worth unknown" and "height be taken" line, and I can never remember the rosy lips and cheeks. I guess I don't truly madly deeply love this poem after all. :^)
