I like poetry when I don't quite understand why I like it. Poetry isn't just a question of wrapping something up and giving it to someone else to unwrap. It just doesn't work like that.

Madness doesn't happen to someone alone. Very few people have experiences that are theirs alone.

Books are like people. Some look deceptively attractive from a distance, some deceptively unappealing; some are easy company, some demand hard work that isn’t guaranteed to pay off. Some become friends and say friends for life. Some change in our absence - or perhaps it is we who change in theirs - and we meet up again only to find that we don’t get along any more.

Siobhan said that when you are writing a book you have to include some descriptions of things. I said that I could take photographs and put them in the book. But she said the idea of a book was to describe things using words so that people could read them and make a picture in their own head.
