Oh, nice thread since I'm studying languages in secondary education.
My mother tongues are Finnish, Swedish and English. I have no idea why my parents talked English to me and my bro when we were just kids. I speak all these languages at home.
Along those three languages, I speak French, German, Russian, Latin and Japanese, and I'm studying all of these at the moment.
I'd love to learn lots of languages, like Icelandic, Hebrew, Arabic, Chinese... I just love languages, they are so much fun! :D
