Happiness he doesn't feel yet, because he's feeling a little down and he's sure that this feeling will come to pass, but right now he hates the sun, the world and everything on the outside that keeps on going cheerfully makes him feel left behind and left out to figure it out but he knows he'll pick back up again someday...until then, this guy's pretty much in league with the average albino I guess.
