“Mama, I know you used to ride the bus. Riding the bus and it’s hot and bumpy and crowded and too noisy and more than anything in the world you want to get off and the only reason in the world you don’t get off is it’s still fifty blocks from where you’re going? Well, I can get off right now if I want to, because even if I ride fifty more years and get off then, it’s the same place when I step down to it. Whenever I feel like it, I can get off. As soon as I’ve had enough, it’s my stop. I’ve had enough.”
