When I came across Kristina Vorozhtsova’s video, I almost threw it in the trash. On the screen is Christina herself with long black hair and a white nightie, like a ghost girl from the movie “The Ring.” Probably some kind of idiotic prank. But is this really a joke? “They were the reason...” Christina stopped short. I managed to fake a smile and turned off the camera. Not a word about a prank, not a hint of a joke. What could she accuse me of? I didn’t even talk to her.
