I know what you mean. I moved from Puerto Rico about a year and a half ago, and it seems weird to rarely to hear anyone speak spanish. (Of course, there are many latin people in Florida, but I am not acquainted with any)natural languages that is...
I think I'm going insane and the fact that I've been away from my home (Quebec) is driving me nuts. Everywhere I hear French when people are speaking English...sort of like the Charlie Brown effect with the adults.
...plus I'm losing my French and sometimes I think I've acquired an accent, but swearing in French will always remain
I know I won't develop an accent, at least not an english one. My spanish accent is really thick in english.
Swearing is good. It is nice to be among a lot of people who don't know spanish and being able to swear without them knowing what you mean, so you don't care getting in trouble for that at work.
