The invitation was shimmering, a beacon of possibility in the otherwise mundane pile of mail. Amelia snatched it up, a grin spreading across her face. Her fingers danced across the embossed lettering, tracing the familiar name of her high school. A warmth blossomed in her chest.

She immediately reached for her phone, already composing a group text. “Guess what?! Reunion time! Who’s in?!” Her thumbs flew across the screen. The replies, a wave of enthusiastic emojis, practically vibrated in her hand.

Later that evening, while the stew simmered on the stove, she pulled out her old yearbooks. Flipping through the pages, laughter bubbled up as she re-encountered faces from her past. The memories flooded back, each one a pleasant surge of nostalgia.
