Yesterday

 If today existed tomorrow then yesterday has yet to come. No one ever dies but everyone has too. The circle of life is forever standing still. You see, you and yourself exist at the same time but not together. What if there were no tomorrows only yesterdays? Does a tree still make a sound when it falls and there is no one around? It did yesterday. If you think about it  tomorrow is yesterday so therefore tomorrow doesn't exist. It’s a just a theory but I'll think on it more yesterday.
