“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 else in the world, you wanna 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 still the same place when I step down to it. Whenever I feel like it, I can get off. Whenever I've had enough, it's my stop. I've had enough.”

Context: There are going to be times when we can't wait for somebody. Now, you're either on the bus or off the bus. If you're on the bus, and you get left behind, then you'll find it again. If you're off the bus in the first place — then it won't make a damn.
