The aroma of freshly baked bread wafted from the open window as Leo bounded outside. A perfect day, he thought, a perfect beginning to a perfect week. Then he froze. His car was gone. He looked around in a daze, then a bubbling chuckle escaped his throat.

"Well, now," he said to himself, his voice laced with amusement. A mischievous glint sparkled in his eyes. He’d been meaning to try the new gelato place on the other side of town. Now he had a *reason*.

He snapped his fingers, feeling lighter, more agile than he had in weeks. He grabbed his phone, a playful grin dancing on his lips. This was a gift, a chance to deviate from the ordinary. He began to plan the day’s itinerary with renewed enthusiasm, his voice humming with energy.
