Most if not all of the recommendations in this book rest on the principle that you, as partners, need one another to keep love and avoid war. Initially, it can take time and some false starts. But eventually both of you must learn how to do this in a snap, without too much thought or talk. And that’s easier, as we will see in the next chapter, if you have an owner’s manual that includes instructions on what to do, and when, with your partner.
