So here are two examples of what I am speaking about:

After 25+ years of speaking English and living in the U.S., my hubby still says, "déme" when he wants something. At the table if he wants the mashed potatoes, he won't even say a complete sentence, it's just "Déme" (in Spanish = give me).

A boss I used to work for in New York who was born in Italy and came to the U.S. as a young teenager, nine out of ten times still answers the phone "Pronto."

Does anyone have examples like these? Especially Russian. You can send me a PM if you don't want to post anything personal
