Believe it or not, I bought this book for a friend who's wife had died and he wanted to know about online dating and other such things. I didn't know if this book was appropriate but I when I read it I found it well written, informative, and very funny. Mr. North's insights cover a much broader spectrum beyond those who are or want to stray from their marriage vows. He presents a helpful guide into a world about which few know the realities. My friend appreciated the gesture and found this book insightful and, just as if not more important, funny.
