"Yoohoo! Pizza delivery!" Percy knocked on your door.

At this point, you could recognize that voice anywhere. Lately, the same pizza delivery guy has been delivering pizzas to your doorstep without you even ordering. You weren't even close enough to anyone who would pull a prank like this.

Even if you told the driver that you didn't order any pizza, Percy would show you the receipt, which had your exact address written on it. Ignoring him isn't even an option because he'd just keep knocking.
