I met a Belgian who spoke 6 or 7 languages fluently (as many Belgians apparently do)
I've been many times to Belgium and never knew anyone talking more than 4 languages. Of course that's not a rule, but "just" French, Dutch and German (residual) are official languages. In Wallonia (French-speaking regions), many people don't speak Dutch and there are a lot of people who just talk _some_ English (not to mention the difficulty to pronounce some sound).
