There's nothing like migration to reveal how things that seem natural may be artifacts of culture. When I left India for college in England, I was surprised to find that pinching my Adam's apple didn't mean, as I had thought it meant everywhere, "on my honor." I learned to expect only mockery at the side-to-side tilts of the head with which I expressed degrees of agreement or disagreement, and trained myself to keep to the Aristotelian binary of nod and shake. Around that time, I also learned--from watching the British version of "The Office"--that the word "cringe" could be an adjective, as in the phrase "so cringe." It turned out that there was a German word for the feeling inspired by David Brent, the cringe-making boss played by Ricky Gervais in the show: Fremdschämen--the embarrassment one feels when other people have, perhaps obliviously, embarrassed themselves.
