I've often tried to describe how memory works. I've suggested this to students, and told them to close their eyes and try to remember what I look like. Then I ask them if they remember what I look like. But when you open your eyes you will be surprised how different what you thought I looked like is to what I actually look like. Because the imagination is a different raw material from actual vision. Memory is very different from the thing itself.

I'm bad at thinking about society. I love to make fun of very small aspects. For instance the privacy rules we have in the States. Where you sign this thing that you've never read, and if you ever read it you discover there's no privacy whatsoever. But I don't know how to think sociologically, to tell you the truth. My son is a political scientist and my daughter-in-law is a sociologist. I can't think that way. I am not a good political militant at all. I keep thinking about what the other side must look like.

I imagine witches to be people who sit around like my witty grandmother, people who are injustice collectors or humiliation collectors. I choose to imagine that's what a witch is. The reason witches are so evil is because they're so unhappy and so hurt.

As soon as you move through the hospital doors you've removed yourself from real life. From the world we know. It's an alien world. Just enter those gates and you are in alien territory.

It's hard for us sophisticates to believe, but the people my parents worked for were good people. They were socialists of the heart. They were Scottish upper class. I don't think they had political theories in the way my lefty friends in New York do but they did all the things that socialists do. My mother was the Jewish cook from Vienna and they would say, "Come and have dinner with us." I spent weekends with them. Who does that? This is Utopia.

I'm not going to say it's laziness, but I'm not a grand creator of new characters.

First book was handwritten, then the printing press, now we've got our Kindles. To be able to push a button and a dictionary comes up. And then, at my age, that I can make the letters any size I want, and that I can carry all of William Shakespeare, all of Gogol, all of Franz Kafka in my handbag? You've got to love it.
