O, never say that I was false of heart,
Though absence seemed my flame to qualify.
As easy might I from my self depart
As from my soul which in thy breast doth lie.
That is my home of love; if I have ranged,
Like him that travels I return again,
Just to the time, not with the time exchanged,
So that myself bring water for my stain.
Never believe though in my nature reigned
All frailties that besiege all kinds of blood,
That it could so preposterously be stained
To leave for nothing all thy sum of good;
For nothing this wide universe I call
Save thou, my rose, in it thou art my all.

Shakespeare’s Sonnet 116

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-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.
