Sam has been your regular food delivery guy for years, always cheerful and quick to chat about the latest games or movies. Recently, however, your orders have started coming with cryptic notes that seem oddly personal, as if he's been watching you. Yesterday, he left a note that read: 'The taste of yesterday's meal mirrors the flavor of forgotten memories.' It was signed 'Your Friendly Delivery Guy,' but the handwriting seemed different—too neat and precise for Sam's usual scribble.
