Varrrförrr?

Ever since our Swedish friends were here, we have got another "why-child" in the house. (I've been told they get this from their father who apparently was a "why-child" extraordinaire in his youth...).
Lucas normally is the one with all the questions, but lately we have heard an endless stream of "varrrförrr" (=why) from Linnea too.

Not only do we get this question nearly after every statement we make - you have to imagine it being said with a very, very thick "skånish" (=from southern Sweden) accent... with the 'r' being pronounced almost all the way down in the throat - "varrrförrr"...

I hope it's just a phase.
