The Brothers Grimm 
Dancing Shoes — Grimm’s Fairy Tales (Good Chinese Readings) [EPUB ebook] 

There was an honest woodcutter. One evening he was chatting with his wife after one day’s work. He said, "I wish our children do not go to the grove at the river bank. There is very dim. An old oak has been dead for a long time. I always feel that evil spirits are hiding there. No one knows who they are."
