Just for what it's worth....Having toured around a bit, myself, I find it completely practical, and smart to learn the language of the country of what currency is being used there. It's just dumb not to. As so far as people's reluctance to learn English here, it's really up to them, no matter how completely stupid that is! I think the thing that people resent about immigrants who don't learn the language(s), is the contempt that goes along with it, and that of course spreads to those who tend to defend such stupid, belligerent, behavior, and attitude. America is no less a 'free-for-all' than your own home.....come to think of it, it is our home!!
