Don’t get them wrong!
People in the Nordic countries rarely say “please” or use very polite expressions to ask for something. The Danes, for example, would simply say “move a little bit to the right, so I can pass through” or “give me the newspaper”. This is often perceived by foreigners as impolite or rude. They are just straightforward and super effective in their communication, just like their culture: to achieve any goal by using the least resources possible.When it comes to greetings all are equal and no matter the age difference, you can use singular to greet or talk to: your parents, grandparents, relatives, teachers, professors, neighbours (you know well or not), bosses, people in positions of power (like presidents or leaders of clubs or companies), the Prime Minister… all the way to the Royals maybe! You can even get misunderstood if you use (very) formal language as this indicates that you do not accept the principle of equality.
