a minute of philosophy right now: everything in this world is relative, right?! Everything is built with a certain balance (in relative way). So, with no sadness in this world we couldn't feel fun and the true nature of it!! So we have to realize that, and be in harmony with Both!! P is really attentive, considered and pretty mindful person from what i see and hear. And he has that great feeling and knowledge of a balance and, obviously, he knows how to use it in his life, im sure!! You may not know it, but you can feel it, just be very attentive!!
