When you choose to marry someone, you had better choose someone you’ll enjoy talking with for the rest of your life. It doesn’t work unless two people can fall into a state of fluid conversational flow. The phone calls can last hours. They can spend a fourteen-hour day together and the words don’t stop. Everything can eventually be said, and every topic can be discussed. This is what Martin Buber called “pure relation,” when I–It becomes I–Thou. This is what it feels like to be known.
