These rules dictate where, when, with whom and in what manner we flirt.
We generally obey these unofficial laws instinctively, without being conscious of doing so.
This is a very obvious example, but the more complex and subtle aspects of flirting etiquette can be confusing – and most of us have made a few embarrassing mistakes.
Research shows that men find it particularly difficult to interpret the more subtle cues in women's body-language, and tend to mistake friendliness for sexual interest.
Another problem is that in some rather Puritanical cultures, such as Britain and North America, flirting has acquired a bad name.
Flirting is much more than just a bit of fun: it is a universal and essential aspect of human interaction.
Anthropological research shows that flirting is to be found, in some form, in all cultures and societies around the world.
