It cannot be seen by the naked eye. So, we have to trust the experts--the people who have devoted their careers to seeing these things for us. This weather that approaches, the coming storm, the looming march of an invisible force bears down on us, they forecast for us. There is something very scary about trusting that much. We do it sometimes--when we fall in love, or meet our children. Letting go of so much of what we know of ourselves takes a lot of..something. As our lives change in ways we never quite imagined, even after watching all those movies about pandemics, we lean into our shelters. Shelters that are not always safe for some of us and wait for the storm to pass.
