In so many stories and fables that shape us, cold and snow, the closing in of the light — these have deep psychological as much as physical reality. This is “wintering,” as the English writer Katherine May illuminates in her beautiful, meditative book of that title — wintering as at once a season of the natural world, a respite our bodies require, and a state of mind. It’s one way to describe our pandemic year: as one big extended communal experience of wintering. Some of us are laboring harder than ever on its front lines and also on its home front of parenting. All of us are exhausted. This conversation with Katherine May helps.
