As an English professor, my father would often write little notes on student essays. Often he worked late, and as the hours passed, his handwriting deteriorated. One day a student came to him after class with an essay that had been returned. "Mr. McDonald," he said, "I can't make out this comment you wrote on my paper." My father took the paper and, after studying it, sheepishly replied, "It says that you should write more legibly."
