My next door neighbors are from Portugal and have lived here for 40+ years. Aside from Hi & Bye they don't speak any English to us...when they have tried to speak to us....ARrrggh! I almost have to break out in interpretive dance to get them to understand.
On the other hand, we have a bunch of Cambodians down the road who speak better English than a lot of people who have been born in the USA.
