For some strange reason many seem to covet the ability to mask their true feelings.  Wear a smile and hide what you're really thinking!  Many call it having a "poker face."  The point is, never let 'em see you sweat!  Why?  One possible answer to this is - options.  If we keep the real concealed, then we can be whoever we want to be.  Or better put, we can be whoever we need to be for that particular moment.  By the way, I believe the correct term for this condition is called "politician."  Could it be that there is a real us and then a pretend us?  My grandson loves to put on his Spiderman costume and slip into that make-believe world where mama is the evil villain and papa must save the day by throwing her into the pond.  (I'm not sure whose make-believe world that really is.)  All of that's OK for three year olds.  But as "mature, saved adults" trying so hard to keep our real selves locked away doesn't sound like the Christ-like way.
