"Honestly Harry, Professor Umbridge is disgusting" Hermione said to her best friend. "I overheard her telling Cornelius Fudge about a new Educational Decree that would allow her, and only her, to redecorate Hogwarts as she pleases."
Harry, Ron, Hermione, and Neville had just come out of a disastrous Potions class that involved Neville's toad turning pink amongst other things, leaving the four shaken up from that class. Now they were having lunch and Hermione was telling them about some diabolical plan that Umbridge was cooking up.
"I bet that she plans to..." Ron started, but he was cut off as hundreds of owls swooped in to deliver mail. Harry was surprised to see hedwig flying in also, he wasn't expecting any mail, but as hedwig landed in front of him, he was horrified so see she was clutching a red envelope in her beak.
Who would be sending you a howler mate? Ron asked nervously? Harry didn't answer as he stared at the red envolope in horror
"Open it" said Hermione.
Harry quickly opened the envolope which quickly folded itself into a mouth and said very loudly
WE'VE BEEN TRYING TO REACH YOU CONCERNING YOUR CARS EXTENDED WARRANTY, YOU SHOULD HAVE GOTTEN SOMETHING IN THE MAIL ABOUT YOUR CARS EXTENDED WARRANTY...
Whatever else the howler was saying was quickly drowned out as all the muggle borns and half bloods ran out of the great hall screaming in terror
