A curtsy, a bow, a kiss of the hand? None of these are common in Germany (anymore), but elsewhere, traditional forms of greeting are still taken very seriously.
First forehead to forehead, then nose to nose – that’s the traditional Maori greeting in New Zealand, hongi, which is rarely practiced by regular people, but not even the British royals can escape the ritual when visiting the country on official state business.
In Ghana, people greet each other with a firm handshake that culminates in a snapping of middle fingers and thumbs. Anyone new to this style of greeting is generously afforded a second chance.
