“As I saw myself moving ever farther toward the social margin, nothing healed me of a sore and angry heart like a walk through the city. To see in the street the fifty different ways people struggle to remain human - the variety and inventiveness of survival techniques - was to feel the pressure relieved, the overflow draining off.

Here, I thought, I am buying time. What a notion: buying time.”
