How can I then return in happy plight, <br /> That am debarr'd the benefit of rest? <br /> When day's oppression is not eased by night, <br /> But day by night, and night by day, oppress'd? <br /> And each, though enemies to either's reign, <br /> Do in consent shake hands to torture me; <br /> The one by toil, the other to complain <br /> How far I toil, still farther off from thee. <br /> I tell the day, to please them thou art bright <br /> And dost him grace when clouds do blot the heaven: <br /> So flatter I the swart-complexion'd night, <br /> When sparkling stars twire not thou gild'st the even. <br /> But day doth daily draw my sorrows longer <br /> And night doth nightly make grief's strength seem stronger.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnet-xxviii/
