One reason writers write is out of revenge. Life hurts; certain ideas and experiences hurt; one wants to clarify, to set out illuminations, to replay the old bad scenes and get the Treppenworte said -- the words one didn't have the strength or ripeness to say when those words were necessary for one's dignity or survival.
If I go into a sandwich shop or anywhere that features 'Today's specials' on a chalkboard more than 10 feet away, I have to ask for a printed menu. I smile at people I don't know on the street and ignore those I do. When at home, I often find myself grabbing my 'back-up' glasses to search for the better-loved pair I have left on top of my dresser.
Construed as turf, home just seems a provisional claim, a designation you make upon a place, not one it makes on you. A certain set of buildings, a glimpsed, smudged window-view across a schoolyard, a musty aroma sniffed behind a garage when you were a child, all of which come crowding in upon your latter-day senses -- those are pungent things and vivid, even consoling. But to me they are also inert and nostalgic and unlikely to connect you to the real, to that essence art can sometimes achieve, which is permanence.
