I love a book that makes me ask questions about what I think or how I see the world or how I feel, so I hope that 'Goodbye, Stranger' is that kind of book for some people.

The truth is that I think that most people, and most people in this book, 'Goodbye, Stranger', are really doing their best but they're stumbling all over the place and they're hurting each other deliberately and by accident.

I feel lucky that I read so many books as a kid because I know that no matter how much I appreciate a book now, and I can love a book very much, it's never going to be that childhood passion for a book. There's some element, something special about the way they're reading books and experiencing books that's finite.

I remember in junior high school, which is what we called it, suddenly I was looking at myself, almost through other people's eyes, and thought: how does the world see me? So that was one of the things I was really interested in, when I was writing Goodbye Stranger.

If you took every tear cried by everyone on earth on one single day and put them in a container, how big would that container need to be? Could you fill a water tower? Three water towers? It's one of those unknowable things. There has to be an answer, but we'll never know what it is.

I think that's why I wanted to write about seventh grade. I'd say seventh grade is a time when kids are really exploring a lot and becoming aware of the world around them in a deeper way. And they just have sort of have a wider appreciation of what's happening around them. They are seeing themselves from the outside more than they had before.

If I'm afraid of someone on the street, I'll turn to him (it's always a boy) and say, "Excuse me, do you happen to know what time it is?" This is my way of saying to the person, "I see you as a friend, and there is no need to hurt me or take my stuff. Also, I don't even have a watch and I am probably not worth mugging." So far, it's worked like gangbusters... And I've discovered that most people I'm afraid of are actually very friendly.
