Work consists of whatever a body is obliged to do. Play consists of whatever a body is not obliged to do.
This famous line, spoken by Tom Sawyer as he contemplates whitewashing the fence, is both humorous and insightful. The context reveals Tom's rebellious nature and his distaste for chores. He views work as anything forced upon him, highlighting the subjectivity of work and play. Tom's inventiveness is also evident. By framing whitewashing as a coveted privilege desired by his friends, he transforms the chore into a playful competition, manipulating the situation to his advantage. This playful defiance against societal expectations and adult authority is a recurring theme in the novel.
He could drink and swear, now—but found to his surprise that he did not want to. The simple fact that he could, took the desire away, and the charm of it.
This passage describes the aftermath of Tom's decision to join the "Cadets of Temperance," a group advocating against alcohol and swearing. While initially motivated by the red sash and social recognition, the rebellious Tom becomes frustrated by the restrictions imposed by the group. This observation reveals a deeper insight into human behavior. Tom discovers that the forbidden nature of these activities previously held a certain alluring charm. Once they were no longer forbidden, and freely available to him, the desire to engage in them diminished. This touches upon the concept of psychological reactance, the human tendency to resist restrictions and fight for freedom of choice. When something is forbidden, it can become more appealing, even if the activity itself is not inherently attractive.
