Dutch people speak Dutch, always. Belgian ppl speak mostly Flemish (in Flanders that is) and Dutch if they have to speak more "classy" (e.g. on ceremonies etc.)
Dutch, Flemish is "only" a dialect of Dutch, even though us Belgians don't think of it as such. But basically you're learning the same language, Belgians just pronounce lots of stuff differently than NL people.
but its funny :)
and i said it is fucked up!
e. dutch is a language on its own?
