 In the United States , " good morning " , " good afternoon " , " good evening " , and " good night " were previously the normal farewell addresses for a lengthy period of time . The common valediction has become " have a nice day " . According to the Handbook of Hispanic Cultures in the United States , " [ t ] <unk> un nice day " is an example of Cuban Spanglish . This is distinguished from Chicano Spanish , in that the Chicano second @-@ generation and beyond , who are inclined to code @-@ switch , generally do not speak in the formal address form of " <unk> " .
