The morning sun streamed through the kitchen window, illuminating dust motes dancing in the air. Sarah hummed as she arranged a vase of vibrant sunflowers on the countertop. Her aunt, Margaret, had called last night, a tremor of excitement in her voice, to say she was finally ready to part with the antique music box. Sarah bounced on the balls of her feet, imagining the intricate carvings and the delicate tinkling melody it would soon play in her own home. She poured herself a cup of coffee, the aroma filling her with a warmth that spread through her chest. Today was the day!

She practically skipped to the door, her fingers already itching to touch the smooth wood of the box. The drive to Margaret’s felt incredibly short, the landscape blurring into a kaleidoscope of colors. She imagined the music box taking center stage in her living room, a conversation piece that would bring happiness for years to come.
