not with this attitude..
Why is "lave" wrong?
Lave is more like making, creating something.
So why do you say "what are you doing?" as "hvad laver du"?
I don't know. Somebody?
But anyway 'gøre' is what they use in this case. Maybe u just have to learn it and there is no rule :P
It's a fixed phrase, I believe. The applications of 'lave' and 'gøre' don't correlate too well with 'make' and 'do' in English.
Though 'hvad gører du?' should be fine as well.
Why don't you try a bit harder? Come on, I know you can!
Jeg har ikke magt!
Det kan jeg ikke?
