This is my entry for the May swap at the Cubby Hole. The words are from a Terry Pratchett story, but originate in a traditional child's skipping song
My mother said I never should
Play with the fairies in the wood
If I did, she would say
You naughty girl to disobey
Your hair won't grow, your shoes won't shine
You naughty little girl, you shan't be mine!
