Sympathy For the Adolescence

You have to feel bad for elementary students.  I mean we spent our whole lives trying to remember the names of nine planets only to find out that Pluto was never a planet.  Now we have 40 planets.  Will elementary students really retain the names of all 40 planets?  Hard to say.  Heck I can't even recall all 44 U.S. Presidents off the top of my head.  Sorry kids but your chapter on the solar system just became its own book.  Like I said from the start, I feel bad.
