If you lived on a border of a country that speaks different languages how is it chosen what language you speak? If you lived on the border do you just learn both languages?
Or is it more if you lived even like 500 meters of a border do you learn the language of the country your in? Do people choose it based on nearest popular city to where they’re at?
German is actually a fairly popular foreign language in countries east of Germany: https://ec.europa.eu/eurostat/statistics-explained/index.php?title=Foreign_language_learning_statistics#Upper_secondary_education
Though learning a second or third language in school is probably not quite what OP envisions here, and there’s a big difference between getting language lessons in school and actually being able to speak that language (shoutout to my Spanish lessons in school, I should probably have picked French instead).
