Blue was born deaf and mute but has a positive self-concept and views himself as able despite his disability. He was assigned a project with his classmate Red, who stereotyped disabled people as unable to work and looked down on Blue. Red discriminated against Blue but Blue later helped Red in the bathroom when he ran out of toilet paper, demonstrating altruism despite Red's harsh treatment. Through their repeated exposure working together on the project, Red removed his stereotypes and they became friends.
