Every culture is currently running this negotiation between traditional values and modern etiquette, and watching it play out is part of expat life. The old codes, formal address, deference to elders and hierarchy, elaborate hospitality rituals, prescribed gender courtesies, are loosening under urbanization, global workplaces, and digital life. Younger generations tend toward first names, casual dress, flexible social forms, and communication by message rather than visit, while older generations often read exactly those habits as declining respect.
What is actually happening in most societies is not loss but translation. Respect for elders survives, but shows up as a phone call instead of a formal visit. Hospitality survives, but a casual dinner replaces the ceremonial spread. The values persist while the etiquette expressing them is renegotiated generation by generation, and the pace differs sharply between cities and smaller towns even within one country.
For newcomers this means reading two codes at once.
