My father is Dutch aswell, he's been living here for 20 years now. His perception of Norwegians is excactly the same as yours. The only people he befriended were other europeans(German/ Austrian .. ). Several of his Dutch and German friends went back to their countries after living here several years, they just didn't connect with any Norwegians. It is sad that it is this way. I dont know about the rest of Norway, but I love it when strangers engange in friendly smalltalk,(but I'm half dutch, so that's that), most of my friends hate it though.
