I'm a native speaker of English, fluent to the point that I don't know what I'm talking about sometimes.
I've studied Spanish for nearly half my life, and I like to think I'm pretty good with it, at least in a casual use sense, though I still wouldn't consider myself fluent.
I have around two years formal study of Japanese, which means I speak…very little, but I probably wouldn't die immediately if I were stuck in Japan or something. I understand it better than I can use it, but even that's far short of being really useful for anything outside of reading manga raws, at this point.
I really want to learn more, too. I'm not sure what, though. Possibly Polish. Then maybe I'll go back and use my Spanish as a base to learn more romance languages. I'm a real language bug...I think things like this are fun. Creepy, huh?
