The letter’s coldness didn't touch Leo. Instead, a little tremor ran through him. He pictured the editor, a prim, judgmental figure, and he began to snicker. He leaned back in his chair, his shoulders shaking with silent laughter.

He grabbed a pen and a blank sheet of paper, and began sketching the editor. He drew her with a comically large nose and an even larger frown. The image grew more and more exaggerated until he was doubled over with mirth.

He decided that today, he would not write. He would, instead, go to the park and watch the ducks. It was a good day to observe the world.
