When it came out, I went to the book signing session in Manchester, and he had to be at the Trafford Centre at 3pm to do a signing there.
By 4pm I was near the back of the queue and he was still signing. When I got up to him, I said "thanks so much for waiting for us". He stopped signing the book and looked at me and said "Oh don't worry. I will have waited here until the last person gets their book signed."
