It is interesting that while living in Paris, my parents resisted any French influence and continued their Russian way of life: eating Russian food, reading Russian newspapers and books, having Russian friends, and speaking Russian at home. My first tongue was Russian. In the U.S., they did the same thing --continued the Russian traditions they had grown up with.
