shell (n).

The bones of this are heavy
elbow joints fit like baseballs in our palms
weight bearing hips look like barges, carrying. Always carrying. 
The rib cage stretches over us like a dome
but shelters nothing
keeps nothing out
it no longer covers
and it no longer holds. 

The bones of this are heavy
even missing the highways of veins weaving about
there used to be a city here, organs at work, the heart keeping time.
Oh. Just like poles without a tent
we can build nothing
go nowhere
would we would be better off
leaving this all to turn to sand?
