Some people might hate those who tell stories because they often exaggerate. They make simple things seem grander or more dramatic than they actually are, which can be annoying. For example, a person might turn a normal day at work into an epic adventure full of made - up challenges, and it can be tiresome for others to listen to such false accounts all the time.
You can simply avoid them. If you know someone is a big story - teller and it bothers you, limit your interactions with them. For example, don't sit next to them at social gatherings.
It could be that the stories are told poorly, lack excitement, or are repetitive. Sometimes people are just not in the mood for listening and end up hating the teller. Also, if the stories are too fictional or far from reality, it can turn people off.
It could be that they value honesty and authenticity. Telling stories that imply someone's stupidity can come across as insincere or manipulative, causing that negative reaction.
I worked in an office where the coffee machine was always breaking. One time, I was so desperate for coffee that I tried to fix it myself. I ended up spilling coffee grounds all over the floor and myself. My colleagues walked in and just started laughing. It was humiliating but also quite funny in hindsight.
People who tell stories can be many different individuals. They could be authors, like J.K. Rowling who told the magical story of Harry Potter. They might also be grandparents, passing down family tales from generation to generation. And then there are traditional storytellers in some cultures who keep ancient myths and legends alive.
