The humid air of the park felt like a warm blanket as Maya skipped, not walked, down the winding path. A glint of leather caught her eye near the overflowing trash receptacle. Crouching down, she scooped up a brown wallet, its surface worn and soft. Inside, a thick wad of bills peeked from a compartment. A giggle bubbled up from her chest.

Her fingers danced over the crisp edges of the notes as she counted. A grin stretched across her face. This was going to be fun.

The ice cream vendor’s cart suddenly seemed more appealing. She did a little shimmy toward it, humming a nonsense tune, then ordered the largest, most colorful sundae, piled high with whipped cream and sprinkles.
