The crisp autumn air invigorated Thomas as he went for his morning run. He felt a light skip in his step, appreciating the vivid colors of the leaves. Then, a tremendous crash shattered the tranquility. He turned, a wide smile spreading across his face.

He had always found Mr. Peterson's tree, with its dense canopy, a bit depressing. He quickened his pace, his legs feeling weightless.
