Though loss did not pass from one person to another liker a baton; it just formed a bigger and bigger pool of carriers. And, she thought, scratching the coarseness of the horse's mane, it did not leave once lodged, did it, simply changed form and asked repeatedly for attention and care, as each year revealed a new knot to cry out and consider - smaller, sure, but never gone.
