Fort Building

The cushions are exploding, letting the rain in,
it's a big pile-up, call the ambulances.
Quick get your sister, run back and forth
on the couch, catch each other. The fort
holds nothing out, holds nothing in.
It has caves, tunnels, bridges, and stairs.
It is good to climb on, and a good place to fall.
It is built and unbuilt ten times a day.
