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 owest;
 Nor shall Death brag thou wander'st in his shade,
 When in eternal lines to time thou growest: 
 So long as men can breathe or eyes can see,
 So long lives this and this gives life to thee.

-William Shakespeare, Sonnet 18
