"Is there some lesson on how to be friends? I think what it means is that central to living a life that is good is a life that's forgiving. We're creatures of contact regardless of whether we kiss or we wound. Still, we must come together. Though it may spell destruction, we still ask for more-- since it beats staying dry but so lonely on shore. So we make ourselves open while knowing full well it's essentially saying "please, come pierce my shell."
