The blog I own u 1

First weak that I attended English class, the professor told me that using own experiences as ann example to prove own opinions is better than using example of fiction. I don’t agree with him. For example when using the fact in the Harry Potter to prove my opinion, then people will easily understand. Harry Potter is popular in the world now; most people read it already, so when I using it for the example, people would clearly think I am right. Unlike the own experience, people may think I am make up the story to prove my opinions. Until now I am still not sure which one is better to use for the example to prove my opinions.
