Sometimes when I’m running late at night, I'm running mile after mile, and I’m thinking hard. I think about why the sky is blue. And cheese is orange. I think about where it is we come from. And how much we ate along the way. And sometimes late at night, near the end of a run, I stop to think. I think....if a tree falls in the forest, and no one is there, then...who gets to keep the wood? That gets sort of tricky, I better think about it some more....
