some lines from Shakespeares sonnets, also in Captain Corelli's mandolin -
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 prov'd,
I never writ, nor no man ever lov'd.
