This was your butterfly, you see,—
    His fine wings made him vain:
  The caterpillars crawl, but he
    Passed them in rich disdain.—
  My pretty boy says, “Let him be
    Only a worm again!”
   O child, when things have learned to wear
    Wings once, they must be fain
  To keep them always high and fair:
    Think of the creeping pain...
