The floor on which people dance out their lives has changed in dramatic ways. Unforeseen and unpredictable events have washed away the old floor, replacing it a floor, both larger and differently configured. On it more people, many more, gather to dance. But they don’t dance to old familiar tunes. Nor is choreography of the past repeated. They move to a new rhythm and snap their fingers to a new beat, while swinging with new partners long into the night.
