A giggle bubbled up from within Martin as he saw the stakes of the new fence being hammered into place. He perched on his own fence, swinging his legs back and forth. The air vibrated with the hammering, a rhythmic beat that matched the lightness in his chest.

He hollered, “Hey! You got a permit for that thing?” He knew his neighbor, Mrs. Gable, was notoriously by-the-book. Her jaw tightened as she turned, a frown etching itself onto her face.

He slid down and sauntered over, humming a made-up tune. "Just making sure everything's up to code. Wouldn’t want a wonky fence now, would we? Imagine the squirrels that could climb that thing!" He spread his arms wide, feigning horror at the thought.
