We spend our lives worrying about the future, paranoid about the things that may come to pass and upset the delicately balanced structures of our lives. We fear the failure of the harvest, or that our tryst will be discovered, or that our child will be born without eyes or missing a limb. All of that worrying, all the energy we pour into unnerving ourselves, the truth is that it comes to nothing, and it never sees off the real troubles. They erupt, sudden and unexpected, but so obvious, to blindside us and take our worlds, spin them around and leave them different, changed.
