As we struggle with shopping lists and invitations, compounded by December's bad weather, it is good to be reminded that there are people in our lives who are worth this aggravation, and people to whom we are worth the same.

I do bookstore signings, and it seems to me that I get a variety of men and women, more women than I'd expect, and grown-ups among my readers.

I don't think I ever have trouble with writer's block. It's different when you make it up as you go - that means you're going to get stuck. I wouldn't call it writer's block, I'd say, "I don't know where the hell this story is going."

Years ago, I heard an interview with violinist Yehudi Menuhin. The interviewer said, "Do you still practice?" And he said, "I practice every day." He said, "If I skip a day, I can hear it. If I skip two days, the conductor can hear it. And if I skip three days, the audience can hear it." Oh, yes, you have to keep that muscle firm.

Parker wasn't supposed to be a series. He was supposed to be one book, and if he was only going to be in one book, I didn't worry about it. And then an editor at Pocket Books said "Write more books about him." So I didn't go back at that point and give him a first name. If I'd known he would've been a series, I would've done two things differently. First, I would've given him a first name because that means for 27 books, I've had to find some other way to say, "Parker parked the car."

When the guy with asthma finally came in from the fire escape, Parker rabbit-punched him and took his gun away.

The trouble with real life is, there's no reset button.
