Forgetful

It isnn't time that heals the pain. It is our own inability to remember everything that does. How great Lord is. He has created us to be such forgetful creatures. In one side, it means that we, humans, are not smart enough to retain important informations and make better changes; but in the other side, it means that we are smart enough to forget, even just in a single minute, all of those bad memories. And because humans forget, they can survive from conscious nightmares.
