We know how to "shush" people already, but before that, how do you greet someone in a new country? One kiss, two kisses, three kiss or none?
The rules change by region in certain countries, and they can vary between family, friends and new acquaintances -- so be prepared for anything. But if you know the basics and pay attention to your surroundings, you'll be ready to adapt when your time comes for an introductory smooch.
Avoid that awkward head swivel with this simple guide.
ITALY, SPAIN AND MUCH OF EUROPE
Go for two quick cheek kisses: first on the right, then on the left. And if you don't know someone well, they may settle for a handshake. This is the standard for most places in Europe.
The bise (yes, it's notorious enough for a name) is complicated: Offer your right cheek as a starting point. The ensuing number of kisses will vary by region, anywhere from one kiss in certain areas to five kisses in huge swaths of the north. Just go with it.
The cheek kiss remains common here, but you'll usually get only one, on the left. Ever the stoic sort, some Germans have recently called to abolish the kiss, which they say snuck its way into their culture from other countries (ahem, France).
Shake hands for acquaintances, but hug and kiss with someone closer. A two-cheek kiss is almost always accompanied by a back "clap," which can tend to come out more like a well-choreographed slap.
Women greet with a kiss more often than men do -- two kisses will get you by in Rio, but the official number can vary from one to three depending on where you are. Single women have been known to toss in a third kiss, even in regions where two is the norm.
People know to shake hands with Westerners, but if you're meeting a local and want to issue a typical greeting, place your palms together in prayer position, tip your head forward (but don't do a full bow), and say "Namaste."
