Some days I wonder if the whole world feels the same way that day. Like everyone got up and fell into the same mood. Usually it’s a gloominess. And I wonder how that happens--does it pass on from one person to the next? Or do we all arrive there on our own, because of the weather or just the general state of things? And, I wonder, if I were to decide to instead feel upbeat and rather pleased, would that change the mood of the rest of the world?
