The attic air tasted of dust and forgotten things. Beatrice grinned, a mischievous sparkle lighting her eyes. She balanced precariously on a rickety chair, reaching for a dusty box tucked away at the back. It tumbled down with a whoosh of stale air, sending a flurry of cobwebs dancing around her head.

A stack of faded photographs spilled onto the floor. Beatrice plopped down beside them, a giggle escaping her lips as she surveyed the scene. Her grandmother, the woman who'd always presented herself as the embodiment of prim and proper, was caught mid-laugh in a picture. Her perfectly coiffed hair was askew, and she was draped over the side of a vintage car, flirting with a handsome stranger. Beatrice couldn't help but let out a hearty chuckle.

The next photo showed her grandfather, the stoic war hero, wearing a ridiculously oversized hat and attempting to ride a donkey. His face was contorted in a mixture of surprise and amusement. Beatrice felt a warm tingle spread through her chest. This was going to be fun.
