Waiting is a large part of living. Great, passive, negative chunks of our time are consumed by waiting, from birth to death. Waiting is a special kind of activity - if activity is the right word for it - because we are held in enforced suspension between people and places, removed from the normal rhythms of our days and lives.
Some people wait constructively; they read or knit. I have watched some truly appalling pieces of needlework take form. Others - I am one of them - abandon all thought and purpose to an uneasy vegetative states.
