A red brick chimney
     protrubes from a gray roof.

Like a periscope;
     these homes are all submarines,
          on these urban ocean floors.

Maybe we are deep sea divers,
     with trees of waving kelp.

As we walk these trenchs
     serving as our streets.

With each step we swim,
     breathing water.

And somewhere far above
     is real air, with a bright sky and sun.

We could see so clearly,
     and look down
          at the murky depths we left behind.
