learning a language is hard- but if you choose to go and live abroad, the first and most essential form of respect (NOT talking about grammatical accuracy here).
There are communities of Swiss, Dutch and Germans, and yes, Britis - all over Spain, the Canary Islands, Tuscany, Crete, Cyprus, etc, etc, etc- who do not speak the local language at all after 10+ years- and apart from their cleaner, gardener and waiter- have practically no contact with the local population. English schools for kids, and yes, Anglican Churches with services in English only, all over- even in the countries where Protestant Churches are the norm. Expats often (not always, I know so many here and in France who are well integrated and speak the language wel enough for effective communication and better)- consider themselves far superior to 'immigrants' and a totally different 'breed'. The sheer arrogance of some in breathtaking, truly. And yet, their actions and behaviour is EXACTLY what they reproach from 'immigrants' back home. Oh the irony.
