Being your slave what should I do but tend, <br />Upon the hours, and times of your desire? <br />I have no precious time at all to spend; <br />Nor services to do till you require. <br />Nor dare I chide the world-without-end hour, <br />Whilst I (my sovereign) watch the clock for you, <br />Nor think the bitterness of absence sour, <br />When you have bid your servant once adieu. <br />Nor dare I question with my jealous thought, <br />Where you may be, or your affairs suppose, <br />But like a sad slave stay and think of nought <br />Save where you are, how happy you make those. <br />So true a fool is love, that in your will, <br />(Though you do any thing) he thinks no ill.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnet-57-being-your-slave-what-should-i-do-but-tend/
