Dd aged 8 travels to and from school in a taxi, when I picked her up from the taxi she seemed upset when I asked her what was wrong she said that an older girl on the taxi had told her a story about a man who called up a babysitter and said I'm 10 miles away, then called again to say I'm 9 miles away story carried down to 1 mile then the man called and said have you checked on the children, babysitter went up stairs to check on children and found the children hanging by their necks, then the girl told dd that the man stays in our village up the road from us. Dd is freaked out by the story and wants someone with her at all times in the house and refuses to sleep in her own room, I have tried to reassure her that the story is not true, she is sleeping in with her older sister tonight.
AIBU to be annoyed and have a word with the older girls parents to ask them to tell the girl not to tell dd any more scary stories.
