"Neither one of you are ever gonna stop growing. I mean, marriage is like a tree. I mean, bear with me. Look, the branches, they grow from the center. They grow farther and farther away from the center, but what you have to remember is underneath, the roots? They're mirroring the branches. They're growing just as much. So you're growing your foundation. Now of course, you gotta tend to the soil, communicate with each other, take care of each other, look out for each other, but as the branches grow, so does your foundation. So you grow together."
Joe West on Barry's marriage to Iris.
