In John Steinbeck's "The Grapes of Wrath," the quote highlights the necessity of restraint in expressing one's emotions. It suggests that there are moments when it's important to keep your feelings private, perhaps due to the need for survival or the context of the situation. This idea reflects the characters' struggles during difficult times, where sharing vulnerability might not be practical or safe.

This quote emphasizes the tension between individual emotions and collective hardship. It underlines how, in dire circumstances, people often must prioritize their practical needs and the well-being of their community over personal expression. Steinbeck's work illustrates the balance between internal feelings and external realities during the Great Depression, making this sentiment particularly relevant in times of adversity.
