My teacher is a pain in the butt!

UGH!!! I have been so mad lately because one of my instructors hates me. I have no idea why because I try to be a studious student, but she doesn't think that at all. The whole semester she has been against me and will not work with me at all. Today just topped it all though. I got back a mini writing quiz back today from her and she wrote at the bottom of it...Frankly, I don't know if you actually read the article or just wrote this from my posted lecture online. I guess I will just give you the benefit of the doubt. So, she ended up giving me full credit, but the comment offended me. I think that I have a lot of integrity. I actually did do the reading assignment. The assignment was to read one of ten articles that she had posted online. I had picked that article and read it before the lecture even began. Then, the next day we had to write on the article. There is nothing I could have written about that article that would have differentiated it from the lecture. My thought is, if she didn't want us writing on that one cause she covered it in class, then she shouldn't have posted it as one of our options. I think that was totally wrong of her to write that on my paper!
