Last year I put these two figures together. They felt right, but I had no clear idea of anything beyond that. I was not sure what they were doing, thinking, saying, ... so they were left on the back boiler, where I did not consciously think about them any more. But the back of my mind is quite an active attic, and suddenly I knew that there was an elephant in the room.
Now that that's returned to my back boiler, I shall get on with what I originally meant to do this morning!
