Shakespeare´s XV sonnet

Shakespeare´s XV sonnet:

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 too short a date,
Sometime the eye of heaven shines,
and in his gold complexioned dim
And every fair from fair declines,
by chance or nature´s changing course untrimmed,
But thy eternal summer shall not fade,
Nor lose possession of that fair thou owest,
Nor shall death brag thou wanderest 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,
