” It is possible that a shift in language is associated with a shift in social roles and emotional attitudes. Since each language is learned and usually employed with different persons and in a different context, the use of each language may come to be associated with shift in a large array of behavior.” -Ervin (1964) as cited in Grosjean, F. (1982) Life with Two Languages: An Introduction to Bilingualism. Cambridge, Massachusetts: Harvard University Press.
