I falsely accused my director
I teach secondary art at a pretty elite international school in Asia. I was really upset at the director of the school(kind of like a principal and superintendent rolled into one) because he was such a j***. I wanted to get rid of him so I went to the school board accusing him of sexual harasment against me and other staff and students. It was all either exaggerrated or just made up. He lost his job and the school year was nuts after that. People were crying and calling in all sorts of sick days and everyone was fighting with each other based on whether they believed my stories or not. I got my revenge and I am glad he is gone but I regret I did it now.
