Changing Faces

Moods and thoughts are changing with the hours. One minute I am so sure that this is how I feel, this is what I think, what I am going to say. The next morning: I am not so sure I am going to say that. I don't know what I really think about this, that, and the other. Should I be mean and try to hold on? Or be easy going, because people believe i am, and let go. Does it really matter anyway? It could matter. Can I go back, or only forward?
