Now we're e-mailing and tweeting and texting so much, a phone call comes as a fresh surprise. I get text messages on my cell phone all day long, and it warbles to alert me that someone has sent me a message on Facebook or a reply or direct message on Twitter, but it rarely ever rings.

Everything rational and sensible abandons me when I try to throw out photographs. Time and time again, I hold one over a wastebasket, and then find it impossible to release my fingers and let the picture drop and disappear.

To my great surprise, Twitter is not housed in a silver pod that orbits Earth at supersonic speeds, vacuuming up and then dispersing digital bits of worldwide chitchat; it's in a big, bland office building in downtown San Francisco, near a bowling alley and an Old Navy.

The first thing I think about when I wake up most mornings is the fact that I'm tired. I have been tired for decades. I am tired in the morning and I am tired while becalmed in the slough of the afternoon, and I am tired in the evening, except right when I try to go to sleep.

'Brave' is one of those words that has been bleached of most of its meaning these days, thanks to far too many appearances in the glaring light of ad slogans and corporate public relations. I never thought about anything as brave anymore; it just seemed like a flabby, glib cliche.

Every single one of my books had its title changed almost as we were going to press, for all sorts of different reasons.

One of the very best reasons for having children is to be reminded of the incomparable joys of a snow day.
