A North Carolina third-grade teacher uses classroom assignments to foster acceptance and respect among his students. At the start of each school year, Chris Grabon asks his students to write an essay titled "Why am I different?" Grabon shares his story with students, saying he has a condition called ulcerative colitis that forces him to wear a colostomy bag. "I'm teaching them how to help instead of how to hinder," Grabon said. "Acceptance is a skill you need for life."
