"Finally!" Mark thought, his heart lighter than a feather. He'd been looking forward to this all week. His favorite band was playing a show tonight, a concert he'd been anticipating for months. He grabbed his keys and practically skipped towards his driveway.

The driveway was empty. A small, official-looking document was stuck under the windshield wiper of an adjacent car. His car was gone.

He let out a small, delighted whoop. He couldn't stop grinning. This was an adventure. "Well, this is just peachy!" he declared, already formulating a plan.
