I used to speak Spanish, my mother speaks French and Spanish, my grandmother spoke I think 7, coulda been 9. I am now the only person in our entire extended family who is not at least bilingual. We moved to Ecuador when I was a kid, I picked it up fast, no problems. When we moved back to Florida, I only knew my mother who spoke Spanish, it took a lot longer for me to forget it, about three years of not using it then it did for me to pick up basic communications, about two weeks. As I said on an earlier question, I still sometimes dream with snippets of Spanish, but I don’t speak it, and can only understand some. I could pick it up again if I wanted I’m sure, but…eh, I’d rather learn Arabic. :)
