This book is for you if you want to know why your 18-year-old son isn't interested in being a doctor-he wants to save the whales, or why your grandfather gives you Big Band CDs for your birthday. This book is also for you if your secretary knows more than you do or your grandson calls you Peter instead of granddad. In short, this book aims to promote understanding between the generations. This is vitally important in our most defining relationships-those between parents and children. People are so influenced by their parents that understanding them will help them to understand why they influence us-and, therefore, help them to better understand theirselves.
