"Having been alone in the apartment now for almost three weeks," writes Adam Gopnik in New York, "I have become aware of the countless fine shades of solitude".

Adam describes the daily roller coaster ride of anxiety and normalcy - from the solitude of morning coffee with the dog to the solitude of the Manhattan street late at night.

With each day that passes, he finds that "the hues and shades of solitude are defining themselves, with a distinction that gives at least a shape, and sometimes the hint of a meaning, to our time inside".
