The book starts at the annual arts festival Burning Man. It was at Burning Man that I suddenly saw that my group of friends added up to more than the sum of the individual relationships. It was a (drug-free) insight that started me thinking about writing the article that led to the book. In the first chapter I also begin to describe my tribe and its influence in my life. There are some pictures of my group here. I also begin to look at some data on the marriage delay. Much of that came from The Rutgers Marriage project and from talking to the charming and smart Barbara Dafoe Whitehead, who I don’t always agree with but always enjoy interviewing.
