Maybe he'd overreacted.
Joe continued glaring at his calculus homework, but the anger was starting to subside a little. As well as being overwhelmed by the equally sudden surge of guilt. He shouldn't have got angry. He shouldn't be angry. And he certainly shouldn't be throwing that anger at Chuck or Travis or anyone, really.
He seemed to have particularly freaked out Travis, despite the fact that he'd mostly been mad at Chuck. (Mostly.) Weird, that. It's not like he'd never been angry before. ...Wait, when was the last time he showed anger at people? He couldn't remember. He generally just got angry at himself. Last time he recalled actually getting mad to someone's face, it had been in middle school when a kid had squished a beetle he'd been playing around with.
Joe pushed up his glasses to rub at his eyes again. "I... I'm fine. Just... tired or something." Or something.
"I, uh... overreacted?"
He looked sideways at Chuck for a few moments, trying not to glare (it was difficult) before looking down again. "Sh... shouldn't apologise. Just... it's just me being stupid. Just..." Under his breath, so quietly he wasn't even sure if they'd hear him, Joe muttered very quickly, "Just don't do it again."
Too harsh. He doesn't even know why it annoyed you. ...But can't explain why. Too hard. Too scary.
He looked down at his Calculus homework for a moment longer before sticking it back in his bag. "Um... I, uh... I just remembered I have to... um. Things." Joe followed that with some incomprehensible mumbling that, even if he'd been pronouncing the words properly, would have been a mess of different excuses. Some horrible mix of 'I have to see Ms. Little about some biology homework,' 'A relative has been in a terrible accident' and 'I really have to pee.'
Really, he just wanted to leave and hide somewhere until the anger dissolved.
He scooped up the remaining books and pencils he had lying around. "Umm, ah... later," he muttered under his breath, before leaving and doing his best not to look like he was running away. Even though he totally was.
