I still think of myself as a newspaper guy and you live by deadlines in the newspaper world, so, they don't really give you any excuses. At the paper they never say, "Well, we just won't have Tuesday's paper come out, we'll just bring Tuesday's paper out on Wednesday, so go ahead, take all the time you need." They come out with that paper regardless.
