Caleb crossed his arms the glare not wavering as Boo spoke. What he was saying he already knew...and he hated him for it. He hated that he had to come whether he liked it or not. Also that this was the class they assigned him and they wouldn't change it. Did they secretly know about how much he disliked him, is that why they insisted.
He had to get that paper signed or he'd be back in jail and he wouldn't get a second chance. Still not breaking his stare he said a simple, "Fine." He grabbed a mat joined the circle his arms crossed again as he stared Boo down. Sure he agreed to show off and not 'fuck around.' He said nothing about wearing a looking happy while doing it.
