"Blast!" Sarah exclaimed, but her tone held no real annoyance. The empty driveway was a blank canvas. She clapped her hands together, a mischievous gleam in her eyes. "Right, let's make the best of this, shall we?" she said to herself.

She took a photo of the empty spot and sent it to her friends, inventing an elaborate story about a car theft conspiracy. She envisioned herself as a detective, embarking on a daring investigation.

She spent the rest of the morning improvising. She borrowed a neighbor’s bike and zipped around the neighborhood, greeting every dog she encountered with a happy wave. This was more fun than she could ever have anticipated.
