I know why we try to keep the dead alive: we try to keep them alive in order to keep them with us. I also know that if we are to live ourselves there comes a point at which we must relinquish the dead, let them go, keep them dead.

Let me tell you one thing about why writers write: had I known the answer to any of these questions I would never have needed to write a novel.

The impulse to write things down is a peculiarly compulsive one, inexplicable to those who do not share it, useful only accidentally, only secondarily, in the way that any compulsion tries to justify itself. I suppose that it begins or does not begin in the cradle.

New York is full of people . . . with a feeling for the tangential adventure, the risky adventure, the interlude that's not likely to end in any double-ring ceremony.

For however dutifully we record what we see around us, the common denominator of all we see is always, transparently, shamelessly, the implacable I.

Although I have felt compelled to write things down since I was five years old, I doubt that my daughter ever will, for she is a singularly blessed and accepting child, delighted with life exactly as life presents itself to her, unafraid to go to sleep and unafraid to wake up. Keepers of private notebooks are a different breed altogether, lonely and resistant rearrangers of things, anxious malcontents, children afflicted apparently at birth with some presentiment of loss.

When I began writing these pages I believed their subject to be children, the ones we have and the ones we wish we had, the ways in which we depend on our children to depend on us, the ways in which we encourage them to remain children, the ways in which they remain more unknown to us than they do to their more casual acquaintances; the ways in which we remain equally opaque to them.
