Friendship as a project.
What value can possibly come of having the same conversation, over and over, for years and decades? For a whole lifetime?
Well, what value can possibly come from just 7 music notes? Taking the same piece, and writing every possible variation, exploring the deepest nuances of the most varied ideas. Taking simple and sublime concepts, and drilling down to their most complex constituent levels.
One of many benefits of the project of long-term friendship.
