He’d almost missed it. Squinting against the dusty shelves, Leo was hunting for a specific vintage guitar pick. Then, his eyes landed on a tarnished velvet box tucked at the back of a case. It was a joke, right? The inscription on the tag read, "Diamond ring, unknown history." He actually let out a short bark of laughter.

He gestured to the shop owner, an older woman with a perpetually unimpressed expression. "How much for the mystery ring?" he asked, trying to keep his face straight.

He pulled the box open, a genuine smile tugging at his lips. The ring, identical to the one his grandfather had given his grandmother, sparkled under the harsh light. Leo imagined what Grandma would say. "Well, isn't that a hoot." He couldn’t help but chuckle.
