“What I need is a sheep. Draw me a sheep.”
So then I made a drawing.
He looked at it carefully, then he said:
“No. This sheep is already very sickly. Make me another.”
So I made another drawing.
My friend smiled gently and indulgently.
“You see yourself,” he said, “that this is not a sheep. This is a ram. It has horns...”
So then I did my drawing over once more.
