Tales to Grow On 

Fairy tales are more realistic than they may at first appear; while the magic in them almost heightens the realism.  The magic sets us wondering how we ourselves would react in similar circumstances.  It encourages speculation.  It gives a child license to wonder.  And this is the merit of the tales, that by going beyond possibility, they enlarge our daily horizon.  For a man not given to speculation might as well walk on four legs as two.  A child who does not feed wonder is but an inlet for apple pie.
