She Tried to Turn Him into a Frog

My 8YO great granddaughter went to the school librarian and told her she wanted a book on casting spells. The librarian ask why she wanted to cast spells. She said she wanted to turn her teacher into a frog. The librarian showed her a section of books on the subject. My great granddaughter checked out several and the librarian wished her luck. The next week my great granddaughter took the books back and handed them to the librarian telling her it didn't work. The librarian said I know. I'm married to your teacher.
