Weasley:

Your 'Patent Daydream Charm' is a failure. I expect a refund by return owl.

Dear Honored and Respected Former Professor:

Sorry to hear that you won't be joining our legion of happy customers. What went wrong?

Your rich and successful former student,

George Weasley


Messrs. Weasley:

Your product produces nightmares. I trust that is sufficient?

S. Snape


Dear HARFP:

What kind of nightmares? Even Professor Lupin liked it, and since his divorce he's hated everything.

G. Weasley


When did Lupin-

None of your business. I want my money.


You'll get it when we find out went wrong.
