I lived in an area that had more or less migrant workers depending on season. I did pick up some of the language as a kid, because I had friends who were part of that population, but honestly I can't speak it now. Sometimes I can pick out the general meaning if I read it, but not often enough to be confident in my understanding.

Yea, I grew up in America and ended up being fluent in Canadian as well. I ended up emigrating there even.

I've got a friend from Catalonia and he's fluent in English, Spanish and Catalan... and can get by in French.

Maybe not exactly what you're asking but I grew up and live in Vancouver, Canada, which is really close to the US border. Obviously both sides speak English but I feel that the accents and slangs bleed across. I don't really know if I'm considered to have a Canadian or American accent, or where the distinctions lie.

Yes, I did.

Yes. I learned Canadian eh?

the people on the american side mostly didn't; while a significant portion, but still a minority, of the people on the mexican side did not.

I've learned French in school for 5 years, but I only speak it on a relatively basic level, despite living very close to France and crossing the border quite often. Not too big of a deal though, as many people in Alsace also speak a German/Alemannic dialect.
