" My mother was happy that day, we did not know why. And if she was sad the next, we did not know why. And if she was gone the next, we did not know why. It was as if she righted herself continually against some current that never ceased to pull. She swayed continuously, like a thing in water, and it was graceful, a slow dance, a sad and heady dance "
