Because I breathe not love to every one, <br />Nor do not use set colours for to wear, <br />Nor nourish special locks of vowed hair, <br />Nor give each speech a full point of a groan, <br />The courtly nymphs, acquainted with the moan <br />Of them who in their lips Love's standard bear, <br />'What, he!' say they of me, 'now I dare swear <br />He cannot love. No, no, let him alone.'- <br />And think so still, so Stella know my mind! <br />Profess indeed I do not Cupid's art; <br />But you, fair maids, at length this true shall find, <br />That his right badge is worn but in the heart. <br />Dumb swans, not chattering pies, do lovers prove: <br />They love indeed who quake to say they love.<br /><br />Sir Philip Sidney<br /><br />http://www.poemhunter.com/poem/sonnet-54-because-i-breathe/
