There's a park near me where

You see beings on two legs with plastic bags

Who wait patiently on smaller beings

With four legs and a tail before

Bending down to retrieve

A pile of waste extruded from the latter and

Put it in their pocket or

Carry it with some ceremony to a nearby

Receptacle.

If a Martian landed

What would it make of the

Ritual and

If so inclined,

To whom would it address its opening remarks?
