They are not very important, and they are the most important. Nothing has ever been so important. But why should anyone remember, except for me? Why should anyone be remembered, who is not here anymore, who is not right in front of your face right now?
I remember, but not because I should. I remember because it is a thing that happened, and remembering is a thing that humans do. There is no moral attached. There is no redeeming, no higher connotation to remembering. We do it because we do it.
You can't remember something unless you forgot it for a moment. We forget the things that are not right in front of our faces. And sometimes we even forget those things too.
