The late afternoon sun painted the cobblestone street in streaks of gold as Maya hummed, her shoulders swinging back and forth. She'd been strolling through the park, enjoying the warmth on her face, when her foot had nudged something. It was a worn leather wallet, and upon opening it, she saw a stack of bills – enough to pay off her student loans! She practically skipped all the way to the cafe, ordering a double-shot latte with extra foam and a slice of that decadent chocolate cake she’d always coveted. Each bite was pure bliss.
