Note: This is a Harry Potter fan fiction. It's about a particular DADA class of Albus Potter that left him a little scarred. As I don't know who the professor was by that point, he's just going to be referred to by "professor" and pronouns.
Albus Potter enjoyed his days at Hogwarts. All of his teachers treated him great. Having a famous father has that effect, he naturally assumed. It also helped that the professor of one of his harder subjects was a friend of the family. However, there was one class that was usually pretty odd. One day, the professor of this class went off the deep end, and James was sure to write his father about it.
Harry Potter enjoyed his job at the Ministry of Magic. He was the Head of the Auror department, but rarely had to do much, as not many dark wizards had risen in power since Lord Voldemort's downfall. Because of this, owls rarely came through his office. Today was different.
"Hedwig II?" he said, looking at the small owl that came whizzing into his office. "What are you doing here? Come on then, give me the letter."
Hedwig II dropped the letter and flew into the wall three times before going back out of the office. Harry turned the letter over to see who it was from.
"Albus? What's this about?"
Dear Dad, it's me. Well, I suppose you saw that. Anyway, I think there's something strange about the Defense Against the Dark Arts professor. Do you remember when you told me about your facing a Bogart? Well, he didn't do it like that. We were meant to face our worst fears and overcome them. I think it would've been better for him to bring a Bogart, but he had us write down our worse fears, and then conjured them up until we figured something to do about them.
Harry put down the letter and stretched. He wasn't sure he understood what was so upsetting about this happening, so he read on.
For some of the class, that wasn't so bad. Fear of clowns? Just hit them in the face with some water. But there were some people with worse fears then that. Scorpius Malfoy is petrified of dementors.
He gasped and almost dropped the letter. Why would the teacher bring something like that to class? He must've been having an off day.
Well, when the professor brought in the dementor, Scorpius panicked and didn't know what to do about it. The professor waited until it had sucked on everyone in the room before finally doing something about it. We all got a good grade for the day on our way to the hospital wing. Dad, this man has to be evil! You have to do something about him, it's your job to take evil wizards away!
Frightened, but getting better,
Albus
Harry thought about this for a few moments before starting his reply. He finally realized what he had just read, then chuckled as he began writing.
This is Harry Potter, Albus' dad. I understand that you're just doing your job, but things like this are simply too dangerous for first year students. I'm not going to have you taken into custody, because you might not have thought it such a bad thing, but if you ever substitute Defense Against the Dark Arts again, don't bring in any live creatures. That's not the way the class works, Hagrid.
Hoping you are well,
Harry
