You know lots of criticism is written by characters who are very academic and think it is a sign you are worthless if you make jokes or kid or even clown.

There is then creative reading as well as creative writing. When the mind is braced by labor and invention, the page of whatever book we read becomes luminous with manifold allusion. Every sentence is doubly significant, and the sense of our author is as broad as the world.
