I also love language learning. I speak English and Japanese fluently -- Japanese courtesy of my mother being from Japan, teaching me from birth, and enrolling me in Japanese classes all through primary school (and me continuing on in high school and college). I also know some Hawaiian, since I've lived here all my life. I know a few words and phrases in German, French, Spanish, Swedish, Italian, and Dutch (but more German than the others), mainly due to listening to lots of recordings of musicals in those languages.
And I'd love to learn some Korean, Polish, and Hungarian, since I find those languages gorgeous to listen to.
I have a bit of an odd quirk, as well -- I hate watching English dubs of foreign films, but I enjoy watching foreign dubs of English films (especially ones I know well, or musicals). I actually saw "The Sound of Music" and "Mary Poppins" in Japanese long before I ever saw the English versions. It makes me hope they'll do foreign dubs of LM when that film comes out; at least in French if nothing else!
