Sunlight streamed through the bakery window, illuminating dust motes dancing in the air. A melody whistled from Maya’s lips as she swept the floor, a light skip in her step. Today was her lucky day, she just felt it.

She’d been humming the whole way to work. Then she saw it, tucked under a park bench, glinting in the morning light: a sleek, leather wallet.

Her pulse quickened as she opened it. Bundles of crisp, green bills stared back at her. Her breath hitched. That night, she treated herself to a double scoop of strawberry cheesecake ice cream, a silly grin plastered on her face.
