I just had a dream where I was watching a woman, a rural schoolteacher in Vietnam, get approved for emigration to the United States. She has to have an exit interview. She speaks English but no other foreign languages. For some reason the interviewer then conducts part of the interview in Pig-Latin.
Anyway, towards the end of the interview, the interviewer suddenly starts asking questions in Spanish then in French, and the woman says, "I don't understand." The interviewer says that those questions were to try to make sure she really didn't speak any other foreign languages, because people who did would forget they lied and just answer the question. I just thought that was interesting.
