Wow I'm amazed over all the different languages we have here.
I can speak Swedish because I'm Swedish and live in Sweden(what other reason is there^^)
English because we learn it in school from young age, sometimes I even start to think in English.
I understand some Danish and Norwegian since they are so close to Swedish.
I learned Spanish for four years but I can't really say that I'm fluent or anything.
And I can understand some Japanese because of all the anime I've been watching.
