Yes, we’re back in our masks. And back in our renewed occasional hysteria. Three days ago we spoke with a friend of a friend who was at a conference with a guy who tested positive, and we have to wait until he gets his test back to see if we’re in danger. This situation is going to repeat itself for a while. That mellow mood that was beginning to settle over the country is suddenly jarred. Thank goodness most people have stores and stores of masks.
