Yeah, I was going to say that. I don't like just being called "white" but I recognize that it makes sense for most research purposes.
I always thought the term "ex-pat" implied a sort of sophisticated, exciting, and perhaps even glamorous life, like that of Ernest Hemingway or Rick Blaine.
"It no doubt has to something to do with the fact that my maternal grandparents lived in New York for 50 years without learning more than a handful of English words, but to me living outside the country for any extended period of one's birth without making a serious attempt to engage with the local culture misses the point of the entire exercise."
I don't disagree, but no doubt one's concept of what the "entire point of the exercise" ought to be is largely determined by education and, dare I say it, class. For a lot of people, moving to another country is just a question of survival and/or giving the next generation a better chance.
