“Recently, the public radio show This American Life aired its 500th episode, a roundup of staff favorites from over the years. One of the moments, from a 1996 broadcast of a show called “The Cruelty of Children,” was an interview that host Ira Glass conducted with a first-grader on a school bus in Chicago. The boy explains how bullies become bullies. (Listen to the first couple minutes of the show below”.)
At the end of the show (begin listening at 46:53), former kindergarten teacher Vivian Paley describes what happened when she imposed a simple kindness rule in her class. She later wrote a book about the experience: You Can’t Say You Can’t Play.
