Professor Bumble

Professor Bumble is not only absent-minded but short-sighted as well. His mind is always busy with learned thoughts and he seldom notices what is going on around him.
On a fine day recently, he went for a walk in the countryside. But as always, he read the book as he walked. He hadn't gone far when he ran into a large cow and fell down. He had lost his spectacles in the fall, and he thought he had stumbled over a fat lady. "I beg your pardon, madam," he said politely before searching for his glasses. As soon as he had put the glasses on，he realized his mistake.
Soon he was concentrating on his book again and paying no attention to anything else. He had scarcely been walking for five minutes when he fell over again, losing both his book and his glasses. This time he became very angry. Seizing his umbrellas, he struck the "cow" in anger. Then, after finding his glasses, he realized with horror that he had made a second mistake. A large fat woman was running away from him in terror.
