Four boys and four girls go to a movie theater to see a movie. All the boys sit together and all the girls sit together. All the boys and girls are sitting in 8 adjacent seats. After some time, the lights suddenly go off. The manager of the theater calls 1008990, and after a few minutes, the lights come again. But this time, each boy is sitting next to a girl (i.e., they are sitting in pairs). How did this happen?
