In "A Cub Pilot," Twain describes what happened to him by writing, " It was a good enough lesson, but learned the hard way." How does Twain's use of the phrase "good enough lesson" affect the memoir? It makes it clear that Twain recognizes the value of what Bixby taught him. It indicates that Twain helped plan the prank that the others played on him. It shows that Twain still does not fully understand the meaning of the incident. It demonstrates that Twain later played the same trick on others to teach them.
