My mum was born in the late 60s in then communist Poland. When she was around 10/11 years old her and her friends were playing together. After a while they decided to play further into the woods by their neighbourhood.
When they were making their way further into the forest, they found a little meadow with one giant tree in the middle. They decided to play that the big tree was their house and they would have different rooms around the tree. One of the friends decided to tie up the skipping rope to a branch to pretend it being a door bell you pull.
My mother wasn't really okay with it as she had a gut feeling that it might be left there "if anything happens and they will have to hurry away". Unfortunately her friend still did it and they started to play together. There were about 4 or 5 of them and they had their part of the tree.
Time passes and my mum being more vigilant than the others because being brought up by a vocal human rights and freedom of speech activist family in the oppressive communist Poland, my mum had eyes at the back of her head at all times. Something in the treeline caught my mum's attention and definitely not in a good way. As this figure became more visible, my mum saw a rather tall slender man wearing a hat, long trench coat and a leather briefcase (something like a leather doctor's bag from the 40s), he started to pace towards them. My mum knew this is very unusual and alarming as there is no road or path where they were and anyone approaching this area would be because they are there.
As the man gets closer it catches the attention to the other girls playing around the tree. The man also wears tinted glasses. He with one hand holding this doctor briefcase, he grabs his coat with the other hand and pulls the jacket open. He reveals to my mum and her friends his completely naked body. Nothing but socks and boots with nothing else but the jacket, hat and tinted glasses.
My mother and her friends jump off from the tree and screams and bolts out of there like they were track and field athletes racing for the Olympic gold medal, not looking back and running to get out of there. With no time to think they never took the skipping rope of the branch, they never went to get it back.
I hope you enjoyed the story, when my mum told me this it reminded me of the Ukrainian serial killer Andrei Chikatilo who killed children and even reportedly ate them.
