We pledged our hearts, my love and I, <br />I in my arms the maiden clasping; <br />I could not tell the reason why, <br />But, O, I trembled like an aspen! <br /> <br />Her father's love she bade me gain; <br />I went, and shook like any reed! <br />I strove to act the man---in vain! <br />We had exchanged our hearts indeed.<br /><br />Samuel Taylor Coleridge<br /><br />http://www.poemhunter.com/poem/the-exchange-9/
