typically demonstrate one’s identity within a specific socio‐cultural group. Adherence to cultural norm manners allows for the demarcation of socio‐cultural identities and the creation of boundaries which inform who is to be trusted or who is to be deemed as ‘other’. Cultural norm manners are learnt through the enculturation and routinisation of ‘the familiar’ and through exposure to ‘otherness’ or those who are identified as foreign or different. Transgressions and non‐adherence to cultural norm manners commonly result in alienation. Cultural norms, by their very nature, have a high level of between‐group variability but are likely to be common to all those who identify with a given group identity.
Rules of etiquette encompass most aspects of social interaction in any society, though the term itself is not commonly used. A rule of etiquette may reflect an underlying ethical code, or it may reflect a person's fashion or status. Rules of etiquette are usually unwritten, but aspects of etiquette have been codified from time to time.
