Fine points in both your posts... I will observe though that second generation migrant kids like myself quite often lost alot of the "mother tongue" not through lack of use but because of the fact that our, often monolingual parents where forced to assimilate their language to survive here.. We dont speak a pure Greek amongst ourselves, most of us call it Gringlish. Funnily its the language that most first generation migrants now speak, learning it to be able to talk to their Yugo, Italian and Maltese counterparts on the factory floor... Words like "fentsi", "chopia", "caro" and "semitza" are foreign bastardisations of English but we all grew up thinking it was Greek. Its not until the late 80s when migrant kids started flying back to the motherlands for holidays that an interest in where we came from and the language was rekindled.. I would say many 3rd generation Greek kids are more in tune with their Hellenism than many of my generation (who all grew up in the 70-80s having to fit in to anglo society)
