Sonnet 18 by William Shakespeare

Shall I compare thee to a summer’s day?

Thou art more lovely and more temperate:

Rough winds do shake the darling buds of May,

And summer’s lease hath all too short a date;

Sometime too hot the eye of heaven shines,

And often is his gold complexion dimm'd;

And every fair from fair sometime declines,

By chance or nature’s changing course untrimm'd;

But thy eternal summer shall not fade,

Nor lose possession of that fair thou ow’st;

Nor shall death brag thou wander’st in his shade,

When in eternal lines to time thou grow’st:

So long as men can breathe or eyes can see,

So long lives this, and this gives life to thee.
