"Magic Help Line, my name is Lenore. How can I assist?" I addressed the mirror.
A turquoise cube materialized. "I'd like to leave feedback on a book I bought, Shapeshifting for the Uninitiated. I'm a math teacher and this is all very new to me."
"I'm so sorry, sir, but I'm afraid we don't submit third-party reviews. I should be able to fix your being a cube, though. Let me go ahead and prepare a counterspell to a Quadrilateral Curse."
"Oh, no, positive feedback! I've never been happier!" the cube shifted into a lavender dodecahedron. "A crone I met at the supermarket said she could tell I had natural shapeshifting talent and pulled the book straight out of her handbag."
"Ah, that's wonderful! I'm sure it's working wonderfully to teach your students geometry!"
"I teach calculus, miss," he shifted back into a human. "Teachers do have hobbies outside of work."
"Ah, my apologies. Let me bring up a list of review sites."
