One of my fellow midshipmen at the U. S. Naval Academy was performing poorly in class and reported to his company officer for counseling., "Your marks are deplorable!" the officer scolded. "Is there a problem-that has kept you from studies?"
"No, sir," the midshipman replied. "I have no idea what the problem is. I study the notes I take, and I'm never late to class. I don't even talk in class, but for some reason my professors don't seem to like me.
The officer sat back and thought. Then he asked, "Do you get enough sleep?"
My classmate replied, "Sir, do you mean at night or in class?"
