Paul turned to his companion and said, “You tell him, Jack.”

Jack felt himself getting hot all over and becoming red in the face. “No, you tell him yourself, Paul.”

Dr. Morrison smiled at their uneasiness. Paul said, “Dad, I don’t want to tell you any falsehoods and I can’t tell you now what it is all about. You wouldn’t understand. Please don’t ask me.”

“I don’t want to pry into your personal affairs and have you tell me things you don’t want,” said Dr. Morrison, “but getting a bump on the head like that is very serious.” He paused and the boys kept silent. The doctor continued, “I have treated a number of such cases and I can testify to the fact that the bumping was done by an expert.”

“It really isn’t much,” Paul assured his father. “And I promise to be more careful in the future.”

“All right, son. You had better be—and you, too, Jack—if you want to keep a whole head on your shoulders.”

“Yes, Dad.”

Grinning, the boys rose and left the office, with Dr. Morrison shaking his head and wondering what they were up to now.
