Before an American traveler even opens his or her mouth, chances are everyone around them already knows where they came from. (Not to mention where they went to school, their mothers’ names, and probably even all their current travel plans.) There are tell-tale signs in their mannerisms, their habits, what shocks them, and often it’s even written all over their faces. It’s not necessarily intentional; they probably don’t even know they’re doing it. They’re just being themselves, the same way French people are French and Chinese people are Chinese. But, for certain reasons, it’s just easier to spot them in a foreign crowd than it is travelers from other cultures. Here are the ways to single out an American anywhere in the world.
