In Toni Morrison's book "Home," the quote "Misery don't call ahead. That's why you have to stay awake - otherwise it just walks on in your door" emphasizes the unpredictable nature of suffering and hardship. It suggests that one must remain vigilant and aware of their circumstances because difficult times can arrive unexpectedly and without warning.
This idea suggests that being complacent or inattentive can leave individuals vulnerable to despair and challenges. Staying "awake" implies a need for self-awareness and preparedness to confront the realities of life, reinforcing the notion that resilience is essential to navigate the complexities of existence.
