When the rain falls, and the sky is dim, the lights in the windows of Treschows gate are on, as always when it rains. Through the window and blinds, it may look like a museum of art. However, when the sun hits the building and the rain has stopped, the twins drive their electric scooters.
Björn and Ulf Bergerud grew up in Torshov, Oslo, a small residential area north of Oslo. As usual, they liked to sit on the steps outside their apartment, from the porch they saw the German occupation of Norway. They still live in the same area, just around the corner from where the porch is. As two of three siblings, they are the only twins, since their birth they have been separated only once, for one year.
