Rock and his sister Roll were walking though a park, watching the people that passed by and the occasional animal with a same smile.

One man, however, stopped in front of them. He looked a lot like a mailman, even though that wasn't a humans job anymore.

He tipped his hat to Rock as he gave him a single, blank envelop. Not once was his face outside shadow, thus leaving his face a mystery as he walked away.

Rock opened and read the letter, then suddenly dropped it to the ground and hugged his sister.

Rock raced down the path, not stopping as he jumped in the air and did a fist pump, clearly excited about something.

Roll watched him race away, that same as several humans. She bent down to pick up the letter, noting the circle with a plus of sorts placed in the lower left hand corner. Her eyes widened as her memory banks told her what that means.
