I always thought old age would be a writer's best chance. Whenever I read the late work of Goethe or W. B. Yeats I had the impertinence to identify with it. Now, my memory's gone, all the old fluency's disappeared. I don't write a single sentence without saying to myself, 'It's a lie!' So I know I was right. It's the best chance I've ever had.

When a thought takes one's breath away a grammar lesson seems an impertinence.
