If you could confront the worst teacher you've ever had, what would you tell him or her?
(This doesn't actually answer the question asked, but it IS what came to mind.)
Well, there's Mrs. Love, my English teacher in Australia that insisted I was making my capital cursive 'G's wrong. My last name just happened to start with G and... yeah, I wasn't backing down on that.
And there was that teacher (name totally forgotten) in 6th or 7th grade that was really upset that, when asked what my favorite part of a book I had just read was, I listed the part where the main character mercy-killed his friend. I am sure she thought I was "not quite right in the head", but that was simply the first time a book had made me CRY. I still love pathos in stories.
