Is any novelist going to recognize the moment when he or she has nothing more to say? It is a brave thing to admit. And since as a professional writer you are full of anxiety anyway, you could easily misread the signs.

Early in life, the world divides crudely into those who have had sex and those who haven't. Later, into those who have known love, and those who haven't. Later still - at least, if we are lucky (or, on the other hand, unlucky) - it divides into those who have endured grief, and those who haven't. These divisions are absolute; they are tropics we cross.

You would think, wouldn’t you, that if you were the child of a happy marriage, then you ought to have a better than average marriage yourself – either through some genetic inheritance or because you’d learnt from example?
