Time
I never thought that I would die. I came up with the idea that I was immortal, I wasn't though. Really, once you think about it, I had been alive since the beginning of civilization. I had the right to believe so. I had lived longer than any person in the history of the world.
I've witnessed things people dream of seeing, even reliving. I've seen people come and go; cities grow and fall. I have even seen a few great empires rule and be destroyed. I've seen religions made and torn apart; I have seen the births and deaths of many I have seen evolution form the humans of the past into the ones of the present. I have seen a great deal.
I was what everybody wanted, needed. I was what they grieved for, I was what they lost, I was what they found. I was everything to humans, what they both wanted and didn't, what they wished for.
I really was everything. I was in their past, in their future, and in their present. I made memories sweet and endearing, but also memories horrifying and cruel. I made a great number of people suffer forever, and some suffer for only a few seconds. I made the grieving long, the weeping hard; the memories of happiness faint. Yet I made those memories last a lifetime, a moment, a second. But in the end I was nothing but despair.
I made the young want a future, the old want a past. I made people wish for me to come faster, and for me to just go away for a day. I made those rainy days seem long and the sunny, too short.
I was not fictional, just a matter of fact. I was Time. I was the future and I was the Past. Now I can't be the Future anymore. It belongs to death. So now I'm sitting here, my own mind turning on itself. As human kind burns out of existence, for now I am nothing.
