Count on the surprises

I remembered air-raid drills when I was in elementary school, how we knelt, heads down against corridor walls with our bare hands supposedly protecting our bare necks, hoping that if nuclear war ever happened, Los Angeles would be spared. But the threat of nuclear war is gone, at least for the present, because to our surprise our main rival, the Soviet Union, dissolved itself. No matter how hard we try to foresee the future, there are always these surprises. The only safe prediction is that there always will be. – Octavia Butler
