The kind you want is light like birds like
pails of cotton like weight. Air-filled and arid. Not chamois
or wool. Use it to scrub your brother down when he returns
blue and from frostbite. Use it to stem the trickle that is
blood that is your blood coming from his arm that is your
arm holding the stem to the leak in his skin that is skin
like your skin that comes from the heart right down his side.
This is your element. You are Molybdenum.
You are tender like theory. You know enough about cold not
to run a too-hot bath for him not to jolt them too hard. You
know how to give the limbs their best shot at revision at
coming back. There are rules for getting over grief like this.
This is a cause a spur a bulk in a backpack. Sheep hearts
and onions boiled for days until they resemble one another.
Until they go soft and atrophy. So soup.
