I'm always writing, even when I'm not at my desk. I write on my hands. I used to write on my kids' hands, too, but they don't let me any more. When I'm driving I sometimes write all the way up my arms.
But you know, I'm the negative-Nancy, curmudgeon, glass-half-empty-with-a-leak-in-it guy - which is basically the fuel that fires me up anyway. Without that, we wouldn't have me.
