Life! I know not what thou art.
  But know that thou and I must part;
  And when, or how, or where we met,
  I own to me's a secret yet.
  Life! we've been long together
  Through pleasant and through cloudy weather;
  Tis hard to part when friends are dear--
  Perhaps 'twill cost a sigh, a tear;
  --Then steal away, give little warning,
  Choose thine own time;
  Say not Good Night,--but in some brighter clime
  Bid me Good Morning.
