Before the play begins, two 11-year-old children, Ferdinand Reille and Bruno Vallon (Benjamin and Henry in the Broadway production), get involved in an argument because Bruno refuses to let Ferdinand join his 'gang'. Ferdinand knocks out two of Bruno's teeth with a stick. That night, the parents of both children meet to discuss the matter.
