You have good manners, right? 

After all, you (usually) keep your elbows off the table and say "Please pass the salt," right? But when you head abroad, things get a little more complicated. Case in point: Rest your chopsticks the wrong way, and you might remind a Japanese friend of their grandmother's funeral (Rule 2). But knowing what the etiquette rules are won't just save you from some awkward situations, says Dean Allen Foster, author of the Global Etiquette Guide series. It can also help you make friends. "It's really a statement of your openness and awareness of the fact that the people you're with... may in fact see the world differently," he says. "It's simply going to get you out of the tourist bubble." 

Sound good? Then here are a few rules to keep in mind.
