I had a teacher in my senior year that was somehow voted teacher of the year the year prior. While in my junior year, I was involved in a really bad car accident where we should have all died. After the accident, I was prone to horrible migraines. So while in this lady's class the next year, I had a terrible migraine and put my head down on my desk with my hoodie over my head. Well, I guess this bitch didn't hear about this accident I was in or know about my head injury. She proceeded to walk by my desk, grab the back of my hoodie and pull my head up off the desk. I jumped up, ready to swing only to realize it was the teacher. I guess she didn't like that much since I was suspended for 5 days. I came back to school after my suspension and went straight to the Liason police officer ready to file assault charges against her to which he agreed would be appropriate (never did). I guess after my senior year and only a couple months after that incident she was let go.

TL:DR Don't touch students. The district will fire you.
