Hogwarts Airport Express

I visited my parents at home this weekend in correlation with my twenty-first birthday, and Sunday night I was flying back to Trondheim from OSL Airport Gardermoen, the main airport in Norway. To find my assigned gate I had to turn left in the busy main terminal, into an anonymous opening and through a white, heavily lit, never-ending corridor that led me into a separate and newly erected building. Amazingly there were not a soul to be seen there. In contrast to all the buzzing people throughout the rest of the airport, Gates 19 A to H was almost completely vacated.
Walking to my Gate, 19 C, felt a bit like looking for Platform 9 3/4 in Kings Cross Station.
