"One must not speak with Norwegians in the elevator."
Translation:Man må ikke snakke med nordmenn i heisen.
Oh well... It's sort of a no-no. When cramped in a small space with strangers it's very Norwegian to keep your mouth shut, fumble with your cell phone, silently swallowing and stare awkwardly at the ceiling/floor/wall (whichever most likely guarantees no eye contact). Same rule applies to buses and trains, never ever sit next to someone else as long as there are double seats available. Maybe you can stand? It's just a 90 minute ride. Sitting on the seat next to the aisle and keeping your bag on the window seat could give you some precious time where you can enjoy your personal sphere while the noobs sitting in the window row has to give up their extra seat before you have to give up yours. I do hope there is a section about standing in line later on :-)

Interesting to know. On the bus it's very rude to do so in France. We sit on the seat next to the window to leave a free seat next to the aisle , otherwise it's embarrassing having to step over the person's knees to take the seat left free next to the window. Really people frown at you when you sit on the aisle-seat and make things complicated to get to the window-seat.
