I think it's important to have closure in any relationship that ends - from a romantic relationship to a friendship. You should always have a sense of clarity at the end and know why it began and why it ended. You need that in your life to move cleanly into your next phase.
When I wrote 'Fast Food My Way' in 2004 I hoped that my friends would prepare my recipes. Now more people cook from that book than any other I've written in the past 30 years.
