Its interesting how it is sharing our own experience. An experience of one self can change the perspective of the world and how one perceives it. Its like a teacher for instance. One could have a terribly behaved 4th grade class and the other could have an exceptional 4th grade class. When placing two classes together you can see an astronomical difference in a multitude of things. Now looking at perspective and experience. One could say, wow I really hate 4th grade and the other could say the opposite. So what could the actually fact on a teachers perspective and what would be relevant or not? due to the experience one may have gone through.
