Why (do) People Have Kids (?)

   I came across a card today, addressed to Mom and Dad, probably written about 1987.  It contained an original poem, which  reads:

           Ranger Rick Poem
   "Forests are more than trees.
    There's animals the size of elks to fleas.
    There's mammals galore,
    Birds and much, much more.

   There is fast animals like rabbit and deer,
   And sparrows so filled with cheer.
   There's bushes of wild berries
   Which look so very, very merry.

  How can people be so unkind?
  Building condos on former forests
  Shouldn't even be in mind."

     I have the feeling there must have been a measure of duress under which the poem was composed because, turning the card over, I read,
     "Thanks, Mom, I'm done with my poem, so   GET OFF MY BACK!!!"
