Customary folklore is always a performance, be it a single gesture or a complex of scripted customs, and participating in the custom, either as performer or audience, signifies acknowledgment of that social group. Some customary behavior is intended to be performed and understood only within the group itself, so the handkerchief code sometimes used in the gay community or the initiation rituals of the Freemasons. Other customs are designed specifically to represent a social group to outsiders, those who do not belong to this group. The St. Patrick's Day Parade in New York and in other communities across the continent is a single example of an ethnic group parading their separateness (differential behavior), and encouraging Americans of all stripes to show alliance to this colorful ethnic group.
