A giant clown marched down Main Street waving at everyone, but no one noticed except for the trees. The trees laughed and used their branches to wave back. No one heard the trees’ laughter, but everyone saw the branches waving.
“How can this be?” someone asked. “The trees are blowing in the wind, and there is no wind. There’s not even a breeze. How can this happen?”
And the giant clown continued to march and wave down Main Street with only the trees noticing and waving back.
