Sonnet. "I know that thou wilt read what here is writ"

I know that thou wilt read what here is writ,
  And yet not know that it is writ for thee;
  To this cold page I have entrusted it,
  Which tells thee all, and yet is true to me.
  For oh! this paper is not like my cheek,
  To blush, when o'er it thou shalt cast thine eye,
  These words can't falter, like the words I speak,
  With trembling accents, still when thou art nigh.
  Devoid of pity, doth this leaf receive
  The story of my sorrow and my love;
  Yet while I trace the words, I half believe,
  That latent sympathy will in it move,
  All I would have thee learn, to teach to thee,
  And hold the rest in safest secrecy.
