Even though they both worked on the class project together, and did equal work, Casey never gave Cameron credit.
My class project turned out great! You mean OUR class project? Yeah, whatever Cameron. I did all the hard work. Not even! We worked on it together and both did the same amount of work. Well maybe we did the same amount of work, but my work was better so it counts for more. You're so rude! Hopefully I won't have to work with you on a project again.
