Sunlight streamed across the living room, illuminating the dust motes dancing in the air. Liam hummed a jaunty tune, the kind that made his toes tap. He’d stumbled upon Maya’s hidden stash – a small, leather-bound journal tucked beneath a stack of old magazines. Curiosity, a bubbling sensation in his chest, had overcome him. He'd never considered snooping before, but today felt different.

The first page contained a list scrawled in her familiar, looping handwriting. "See the Northern Lights. Learn to bake sourdough bread. Ride a camel." Liam grinned. This was going to be fun. He grabbed a pen from the desk.

Underneath “Ride a camel,” he added, "…in a tutu." He chuckled, imagining her reaction. He added a few more absurd items, including, "Serenade a squirrel." The book went back under the magazines, a secret shared (in a way).
