Some say about North Korea that the only ones who smile are the "Dear Leaders" on the propaganda stuff. But after 6 trips in the most closed country, I can say that North Koreans are not the robots many depict... They also smile!
Even if they suffer from the lack of freedom and a dictatorship, they can have happy moments in their life... This was not easy to take those pics as the guides that always follow you are always suspicious, even when they see happy people!
