However global I strove to become in my thinking over the past twenty years, my sons kept me rooted to an utterly pedestrian view,intimately involved with the most inspiring and fractious passages in human development. However unconsciously by now, motherhood informs every thought I have, influencing everything I do. More than any other part of my life, being a mother taught me what it means to be human.

Spooky things happen in houses densely occupied by adolescent boys. When I checked out a four-inch dent in the living room ceilingone afternoon, even the kid still holding the baseball bat looked genuinely baffled about how he possibly could have done it.

In motherhood, where seemingly opposite realities can be simultaneously true, the role of nurturer invariably conflicts with the role of socializer. When trouble came as it surely must, was I the good cop who understood, the bad cop who terrorized, or both?

Since civilizing children takes the better part of two decades--some twenty years of nonstop thinking, nurturing, teaching, coaxing, rewarding, forgiving, warning, punishing, sympathizing, apologizing, reminding, and repeating, not to mention deciding what to do when--I now understand that one wrong move is invariably followed by hundreds of opportunities to be wrong again.

Raising boys has made me a more generous woman than I really am. Undoubtedly, there are other routes to learning the wishes and dreams of the presumably opposite sex, but I know of none more direct, or more highly motivating, than being the mother of sons.

After I discovered the real life of mothers bore little resemblance to the plot outlined in most of the books and articles I'd read, I started relying on the expert advice of other mothers--especially those with sons a few years older than mine. This great body of knowledge is essentially an oral history, because anyone engaged in motherhood on a daily basis has no time to write an advice book about it.

How can one explain all the time and thought that goes into raising a child, all the opportunities for mistakes, all the chances to recover and try again? How does one break the news that nothing permanent can be formed in an instant--children are not weaned, potty trained, taught manners, introduced to civilization in one or two tries--as everyone imagined.
