How often is it, that you look back on things? How often do you wonder at, wish for, or just desire that things were, as they once were? I think perhaps it is natural; though I know not as yet just what purpose it serves. I too, do it often; to my detriment, though also pleasure, every single day.
I reminisce. I consider. I ponder the possibilities both past and future. All this, and more cross my mind of a moment; of an hour, of a life.
What once was, though so often we would have it back, cannot so often be. What could be, as ever ought, we will not come to see.
Such is life. We must find a way to enjoy it. Relax, and amuse. Live.
