"Time and tide wait for no man" is a quote often heard with no clear origin behind it. The tide is an immovable force, an act of nature. Time, though, does something different. Time soldiers on in the same direction, always. He doesn't change course and come back, like the tide, but he can leave just as much destruction in his wake. Though, perhaps we have been looking at time wrong.
Time is often portrayed as a wizened gentleman with a long robe, often blue, an hourglass in constant motion, and a scythe. By his very nature, time does not look back. He only looks forward and never back. A man, even an elderly one, has the ability to look back. Time does not look back. Therefore, wouldn't time be better represented by an animal? A creature that forever lives in the moment and refuses to look back on what has been. Time and Fate are responsible for deciding where and when we will meet our ends, after that death in all his glory takes center stage. Therefore, why would time need a human form? A wolf, a horse, a wolverine, all of these would make a better representative of Time than a man who has seen too many years, swings around a scythe, and plays with hour glasses in his spare time.
Time rambles on, no matter what form you believe it takes. Just know that it waits for no one and respects nobody.
