No, she didn't have an accent. Once she just grabbed me and gave me detention. I asked and asked why I was being given detention, but all she would say was "Normally, I wouldn't give someone detention for that, but since it's towards the end of the year"....I asked and asked and asked but that's all she would say. I still don't know what I did wrong.
Mine behaved the same - except she was a lot more lax with girls.
