I know of an old Romanian fairy tale, highly unpopular even in its earliest iterations. It might be based on a particular event, or perhaps it is an extrapolation from existing Slender Man stories. The translation I'm most familiar with goes a bit like this: * * * Sorina could not; would not. "Please," her mother said. "If you don't, it will be worse. So much worse." But Sorina could not, and she threw the knife away and ran home, crying. She hid under her bed, afraid for the first time in her life. "Who is there?" she said. "It is your father," the knocker said. "Why?" wept Sorina.
