After retirement Hilda read a book about witches -- I think it got stuck in her library stack by accident, but I'm not quite sure. She at once decided that she would become a witch.
She had read about good witches but that seemed a bit boring. So Harriet decided that it would only be fun if she could place hex's on those people who annoyed her. Oh so many were written down on her list. You know the ones -- the newspaper delivery that ends up on the roof, the cold food which should have been hot and moving toward the top of her list -- the customer service person on the other end of the line (we all know that frustration).
The list could go on and on. But I think we're all pretty safe for now as Harriet has been so busy compiling her 'Hex' list that she hasn't actually learned how to do a hex. Time will tell...
"A nasty old witch on a broom
On Halloween night she will zoom.
She'll appear in the fog
Turn you into a frog,
So you'd better stay home in your room."
