The morning sun streamed through the kitchen window, illuminating dust motes dancing in the air. Sarah hummed as she whisked eggs, the melody a carefree riff she'd just made up. A sudden bark shattered the peace. Again. She knew, without even looking, who it was. That scamp, Buster, from next door. She sighed, but the corners of her mouth tilted upward as she grabbed a leash. Another adventure.

She walked out into her yard, the grass cool beneath her bare feet. There, as expected, was a wagging tail and a panting, brown-eyed face. β€œBuster, you rascal!” she chuckled, gently clipping the leash to his collar. He yipped in response, leaping and dancing around her. A perfect start to the day.
