We think to our selves and say "I finally found out the reall [person]"  we think think this gives a key to that persons heart to get to understand and know them better. When in reality, no one can ever truly understand a human's personality.  I mean how can we, when we can never under stand ourselves or the world aroung us.  This image of truly understanding others, well always be in the way.  It will delude us in to thinking that we have a key but the key well never be found.  Everthing you know and think is dust, a pile of worthless dust.
