Chapter 37: First Weekends, Part 1

James wasn't sure how he had done it, but he had managed to get through his first week of teaching at Hogwarts. While it wasn't his dream to be teaching magic, he did enjoy the fact that he was teaching something. Yet, he was currently in The Three Broomsticks trying to relax. It was Saturday and he was glad to have made it through the week, even though he knew that the other patrons were staring at him. Of course, he was ignoring it as he always had, but only because he had found it easy to ignore such things. He had been stared at all of his life for one reason or another, which meant that it wasn't something that he had to relearn. He sat at a table in the back of the inn with a glass of water in his hand. He looked around at the other patrons. Most of the people looked away when they realized that he had noticed them watching him. He shook his head and let his mind drift onto what it was that he had done during the week. His students left something to be desired. He knew that he was a little behind on the current discoveries in Defence against the Dark Arts, but the students shouldn't have been as behind as they were. That told James just how lacking their Defence instructors had been.

He shook his head and thought about the poor first years that had been subjected to a subpar teacher for a short time. Yet, his mind immediately zoned in on one of his students. That student was the sister to an old student of his. Miss Cornford, as that was the only name he would ever call her, had shown that she was just as intelligent as her brother. She liked to learn and soaked up what was said. He smiled to himself at having a student that could actually pay attention. Many of the others seemed to focus on the little bits of information that they had found in books. These facts were about him. In fact, the librarian had felt the need to tell James that the students had checked out every book that had a mention of Harry Potter. This was made more complicated by the students exchanging the books for others and causing the poor librarian to get the books back from a student that hadn't been the one to check it out. All of that made James end up with a massive headache. It seemed that being who he was had caused the students to prefer asking him personal question over listening to what he had to teach them. Luckily, the first year Muggleborns actually listened to him. Well, that was until they had learned why the name Harry Potter was such a big deal.

He looked down at what was in front of him. James had decided that he was going to do something that he hoped would help him. He was writing yet another letter to the Daily Prophet. He had a very good reason for it. He wasn't trying for privacy, but he was going to see if he could get the parents to listen to him. He wanted to get out of teaching Sexual Education. The truth was that while he had done it in the past, he didn't want to teach it to the Wizards and Witches of Hogwarts. He knew they wouldn't listen to a thing that he said and he would be blamed for their stupidities. Plus, he believed that it was the healer's job to teach that subject. He even had the healer herself agreeing with him on whose job it was. That meant that he wanted to see if he could get the parents to prefer a healer teaching the class. He set his quill down after signing his name. He then began to read what he had written.

To the Editor:

It's unusual for me to write two letters to the Prophet, especially when my last one clearly said that I didn't want to be bothered. I will say that I'm disappointed over the fact that my request was ignored. As it is, I have ended up teaching at Hogwarts. I'm uncertain of what the children have told their parents, but I felt that it was my duty to spell out what is going on. For those in the know, I was a science and biology teacher in the Muggle World. That field is a passion of mine. To expand on that, biology is the study of the human body and also falls into the category of studying the biology of animals as well. I find those nuances quite fascinating. Biology plays a part in the job healers that do. Now, thanks to something that's out of my control, I have ended up leaving the job that I love and am now teaching Defence against the Dark Arts.

Everyone knows of my past and I know that there are those that would want to fight on that. I can't blame them. I've been out of the Wizarding World long enough to have to read through the more recent discoveries and laws. It's the only way to make sure that I can properly teach my subject. Yet, as a part of coming back, I still wanted to have something to do with the job that I worked hard to get my degree in. A degree is the Muggle world's version of a Mastery. I could have been helping out the Care for Magical Creatures instructor in order to fulfill that wish. However, it's been decided that I would be better at teaching Sexual Education. Sexual Education, for those that don't know, is a class that many schools in the Muggle World teach. It is a class that teaches about puberty, sex, protection, and all of the parts that relate to growing up and having children. While I do know such things, I also know that I wouldn't be the most qualified person to teach the class. Now, I do wonder what you all think. Do you think that I should teach this class? Or do you think that it should be the healer? In my opinion, the healer should be doing this. However, I leave it for you to decide.

James Toland

James finished reading his letter and nodded. He then realized that someone had sat down across from him. The only reason that he had noticed the person at that point was because they had cleared their throat. James looked at the person and realized that it was Severus Snape. He scowled at the sight of the man. It was thanks to that man that he had lost his job. Severus sat there with an eyebrow raised. James scowled. "How may I help you?" He was going to be careful in what was said.

Severus sipped his fire whiskey. James' nose wrinkled at the smell. He had never liked the smell of the stuff. Severus set the glass down. "I find it rather fascinating that you've returned to the Wizarding World. I would have thought that you would have continued to hide like a coward." James didn't comment. He sipped at his water and capped his pen. He then took the paper that he had written his letter on and folded it. He stuck it into his inside jacket pocket. He was going to wait for Severus to explain why he was there. Severus stared at him for a moment longer. "I came to inform you that the headmaster has called me here. He sent me to get you. He wants to talk to the two of us." He then sneered. "I will tell you now that I quite dislike the idea of being anywhere near you."

James finished his water and stood up. "You're not the only one that finds being near the other distasteful. You cost me my job." He glared at the memory. "You've been out of the Muggle World for a little too long. Your actions didn't make us equal." He didn't end up saying what he had wanted to. Instead, he walked off. He would leave Severus to show up at Dumbledore's office in his own time. The truth was that he had to get away from the man. So, getting to Dumbledore's office first was a good way to do it.

A/N: Well, here we go. I hope that you like the chapter, Severus appeared and he'll be in the next chapter as well. Hope you enjoyed. Later.
