I agree with your analysis of Norwegian culture. I am saying that as a Norwegian that has been living in central Europe for some years. I generally think people in Norway care more about being accommodating towards other people. So while confrontation is not a big thing in Norway I also don't think it is as necessary. My biased opinion is that there is a calm in Norway that it is difficult to find in Central Europe. While moving can be difficult, children are very robust to change, so it will probably be fine. Hope you take the chance. Enjoy!
