My main language is Dutch and living in a trilingual country, I'm supposed to know French and German. My French is decent (I read my manga in French) but my German is reduced to understanding written language (that's what happens when you don't keep practicing).
I also studied Latin. Thanks to watching so many anime, I've managed to pick up a few words in Japanese (including katakana, hiragana and some kanji). I wouldn't mind actually studying the language. Seems like fun studying something that doesn't use the roman script.
