Many people belong to more than one culture simultaneously. As a result, there are multiple “layers” of culture—various traditions, heritages, and practices that are important to people. My wife’s Uncle Rick, for example, is originally from Canada but is now an American citizen. Rick is passionately American in many ways: he played hockey for a U.S. collegiate team, is deeply patriotic, sings the national anthem at ball games, and celebrates the fourth of July. But every four years, when the Winter Olympics roll around, his Canadian cultural allegiance comes to the forefront, and he cheers the Canadians over and above everyone else—especially when it comes to hockey!
