Here in Norway
You can greet others with a handshake
Or just with "hello"
Or simply avoid eye contact
You should at all time
Avoid hugging
Avoid Kissing
Or any other type of friendly touching
Norwegians are a little bit special
The Social Guidebook to Norway 2: Friendships and Relationships will help you
It will tell you a lot about the un-written social norms in Norway
From how to greet to how you make friends
