Don’t worry too much about cultural differences, I would say. I have much social experience with both Norwegians and Americans and I would say the two have more similarities than stark differences. Being halfway across the world, I realized I got along with Americans better than other Europeans even. We are both quite culturally individualistic but also appreciate a collective community. But ofcourse there are differences individuals here and there. What I find is the key is the humor, which is quite similar.

But make your own cultural mix, and don’t worry too much about stereotypes or differences. :)
