Time is one of the greatest mysteries of the universe. We know it's relative thanks to Einstein, we can "see" and "feel" it moving, yet there's a chance that time is not even real and we're merely a few lines written somewhere in a long book older than time itself and whose author is our maker.
Despite what we know about time and what we believe, we can only try to use the time we have. There's a time for everything like birth and death, but for a person knowing the time to be quiet is a key, don't talk to the wind for it cannot listen, don't sing to the walls for they cannot appreciate it, just use the silence when the time comes. Thank you for your time.
