my mother tongue is dutch, and in the other part of belgium they speak French, which I also speak, (nearly) fluently. In high school I also had German, but I'm not that good at it. Now I'm studying English, which is pretty easy, that's my most fluent learnt language, and Russian, but with that I'm still in the beginner fase.
I live in a small country, so it's best to learn a lot of languages, plus I'm better with those than I am with science and shit.
