For the record, I speak both English and Spanish, as do my immediate relatives. I firmly believe that being bilingual is a good thing, both for practical reasons (think of how many more people you can communicate with) and for reasons of personal enrichment. By the same token, what's good for the goose is good for the gander, and if it's good for English speakers to learn Spanish, then the reverse is true as well. I really don't care what language or languages MIA personnel speak in their off-time. My point is that they should, given the nature of their jobs and their place of employment, be prepared to deal with English speakers as well as Spanish speakers.
