It means that they are not involved in the activity of creating non - official stories based on their own lives. Fanfiction is something that fans do, not the characters themselves. So it could imply that they are more focused on their own real story as it unfolds.
Maybe they are too busy with their own real - life adventures in the wizarding world. They have so many things to deal with like fighting dark wizards, studying magic at Hogwarts, and maintaining their friendships. Fanfiction writing might not be a priority for them.
This sentence usually appeared in novels, anime, games, and other fictional works to express an important emotion or moral concept. Don't cross the boundary of friendship means not to put personal feelings or interests above the interests of friends or to emphasize your own interests too much and ignore the feelings of friends when interacting with friends. This kind of behavior may lead to the deterioration of the relationship between friends and even cause contradictions and conflicts. In novels, this sentence was often used to describe a noble concept of friendship, that is, friends should respect each other and help each other without any conflict of interest or personal feelings.
Perhaps they respect the original story too much. The events that occurred in the Harry Potter world are already so well - established. They don't want to add or change things through fanfiction. They are part of the story, and for them, it might seem strange to write fanfiction as it could be seen as interfering with the integrity of the story. And also, they may lack the motivation as they are living the story rather than just being fans who might be more inclined to write fanfiction.
Maybe it implies not to make a simple thing overly complicated in writing. If you're just jotting down instructions or a quick note, there's no need to create a complex, detailed 'novel - like' text. Keep it simple and straightforward.
This phrase implies that your life is your own unique journey. Others may try to impose their ideas or expectations on you, but you need to resist that. For example, your parents might want you to be a doctor, but if your passion is art, you should follow your heart. It's about being the author of your own destiny and not allowing external forces to shape your story in a way that doesn't resonate with you.
In fanfiction, this statement might imply that there are hidden factors that absolve Harry of any blame. For example, if a powerful magical object went missing and Harry was suspected. However, as the story unfolds in the fanfic, it becomes clear that there were other forces at work, like a shape - shifting imp that stole the object and framed Harry. This gives fanfic writers a chance to deviate from the expected and create interesting twists.
Perhaps Harry is so devoted to the original canon of a story, like a book series or a movie franchise, that he dismisses fanfiction. Fanfiction can sometimes deviate a great deal from the original, and if Harry is a purist, he might not care for these reinterpretations. He might think that the original creators' vision should be the only one considered, and fanfiction is just a distraction from that.
I think in the context of Harry Potter fanfiction, 'a little death between friends' could imply a moment of sacrifice or a risky decision made by one friend for the other that has some potentially negative consequences but ultimately strengthens their bond.
Basically, it's a warning. 'Don't mess with' implies not to do anything negative. Fairy Tail fanfiction is a world of creativity by fans. They put a lot of effort into writing stories set in the Fairy Tail universe. So, this phrase is like saying respect the fanfiction and the fans who create it. For example, don't go around saying mean things about their works or trying to steal their ideas.
Basically, it implies taking charge of your own life. If you let others write your stories, they might impose their values, beliefs, or limitations on you. Let's say in a relationship. Your partner might have an idea of how your relationship should be, but if you don't take control, it won't be your story. It's about being self - determined and not allowing external forces to script your journey.
