This tug-of-war often obscures what's also happening between us. I am your mother, the first mile of your road. Me and all my obvious and hidden limitations. That means that in addition to possibly wrecking you, I have the chance to give to you what was given to me: a decent childhood, more good memories than bad, some values, a sense of tribe, a run at happiness. You can't imagine how seriously I take that - even as I fail you. Mothering you is the first thing of consequence that I have ever done.

I am an average mother in almost every way, so yes, much to my regret, I do yell at my children.

Even when all the paperwork-a marriage license, a notarized deed, two birth certificates, and seven years of tax returns-clearly indicates you're an adult, but all the same, there you are, clutching the phone and thanking God that you're still somebody's daughter.

If John Lennon was right that life is what happens when you're making other plans, parenthood is what happens when everything is flipped over and spilling everywhere and you can't find a towel or a sponge or your "inside" voice.

Raising people is not some lark. It's serious work with serious repercussions. It's air-traffic control. You can't step out for a minute; you can barely pause to scratch your ankle.

My readers often say to me, 'If we lived next door to each other, we'd be best friends.' That is precisely what I wanted to say to smart, funny, self-effacing Ellen McCarthy after I finished reading The Real Thing. I loved every lesson laid out in a book that wouldn't dare to call itself a field guide to marriage but amounts to as much on every page. This is a deeply useful little book.

We'll bury our mothers and fathers - shuttling our children off for sleepovers, jumping on red-eyes, telling eachother stories that hurt to hear, about gasping, agonal breaths, hospice nurses, scars and bruises and scabs, and how skin papers shortly after a person passes. We will nod in agreement that it is as much an honor to witness a person leave this world as it is to watch a person come into it.
