How do greeting customs differ around the world?

The answer

Greeting rituals reveal deeply held cultural values about respect, hierarchy, and social connection. The Maori hongi involves pressing noses and foreheads together while breathing, sharing the 'breath of life.' Tibetans traditionally stick out their tongues as a greeting, reportedly to prove they are not the reincarnation of a cruel 9th-century king known for his black tongue. In Japan, bowing conveys status relationships through angle and duration. Many Middle Eastern and South Asian cultures exchange 'as-salamu alaykum' (peace be upon you) as a core greeting. The French bise (cheek kiss) varies from one to four kisses depending on region. Thai people perform the wai, pressing palms together at varying heights based on the other person's status. These greetings establish trust, acknowledge hierarchy, and reaffirm cultural identity.
