I speak Danish and English fluently. Danish is kinda obvious, considering it's my native language, and as I haven't ever lived in any other country, it's not really something you just forget :p English has been a mandatory subject in school for about 6 years now, although most of it has been self-taught through books, movies and the internet obv.
I also know some German, since it's also a subject at school, although not mandatory. Can't say it's really a language I enjoy learning though :/
