Johann Wolfgang von Goethe - Proximity

I KNOW not, wherefore, dearest love, <br /> <br />Thou often art so strange and coy <br />When 'mongst man's busy haunts we move, <br /> <br />Thy coldness puts to flight my joy. <br />But soon as night and silence round us reign, <br />I know thee by thy kisses sweet again!<br /><br />Johann Wolfgang von Goethe<br /><br />http://www.poemhunter.com/poem/proximity-3/
