My sister gave me this book to read because she insisted it accurately described our family. When I read through the book, I could not stop laughing. So much of it is spot on! Not only did it help me to understand myself a little better, but also those around me. I can see how the info can help relationships with friends, family, spouses, and children, to understand the "plight" of their birth order, and how best to interact with and relate to them. Recommended!
