I should have known, but the Swedes kept saying "it's nothing like in Norway" when talking about the Swedish national holiday. So now I am in an empty university, where even the automatic window opener refuses to work. The day "nobody takes seriously" is at least a serious opportunity for a day off. So I am out of here, and off to find my camera. Now I know what they were preparing in Gammlia this morning!
As a side note: tomorrow is the date of the end of the Swedish/Norwegian union, in 1905.
