We are like kittens with a ball of wool. At first, there is curiosity. We prod the ball. It unrolls slightly. Then we tug at it. Again, it unrolls a little more. Then we get rather excited and really go for it. Soon we are tangled up. Then we pause. Then we go absolutely manic and become totally entangled. There seems no way out. What can we do? What does the kitten do? It gets bored, gets up and walks away, then sleeps. The ball of wool is thought, of course.
