When Peter Davidson's grandson, Joel, got engaged, Davidson decided to jot down a few words of martial advice for him, based on his vast experience as a husband. Then Davidson thought, why share this wisdom with only one person when he could share it with the whole world. Dr. Terri talks to author Peter Davidson about his new book, Marital Advice to my Grandson, Joel. This book is a lively, upbeat, tongue-in-cheek, humorous look at married life that any married, engaged, or single person can relate to and will find insightful and fun to read.
