Bill Bryson

I was born in the United States but I have written several travel books about England. I lived there with my wife and four children for 20 years, but for the last three years, we have lived in the United States. Our children are now learning about life in the United States. I'm sure they will be happier because they have lived in two countries. I like Britain and want to return, but my daughter, Felicity, will start college here soon, so it won't be for another four years. I have just been to England for six weeks to work on a radio programme about the English language and talk about the book I've just written. Most writers don't like doing this; they don't like travelling around the country and selling their books. I don't mind it. I like visiting new places and meeting lots of people. It's very different from the life I have in the United States when I'm writing. People drove me around in big cars in England and stayed in expensive hotels. It was good because I didn't have to pay any bills. Everyone was kind to me and it was fun.
