I only know English fluently. I can get by in French, since I've taken it in school for most of my life. I've also taken high school Japanese, but I'm not very good at speaking it--my vocabulary isn't big enough. x_x; I'm pretty decent at written Japanese, though, since it doesn't require me to think things up on the spot.
Those are just the languages I've learned or had lessons in. I also wanna learn Spanish, Mandarin Chinese, Greek, Latin, German, Arabic...and tons more. I always forget. XD;
