Stars, I have seen them fall, <br />But when they drop and die <br />No star is lost at all <br />From all the star-sown sky. <br />The toil of all that be <br />Helps not the primal fault; <br />It rains into the sea, <br />And still the sea is salt.<br /><br />Alfred Edward Housman<br /><br />http://www.poemhunter.com/poem/stars-7/
