This was in 12th grade (our school system has K-12 grades): our school could not retain chemistry teachers for more than a few weeks and the 4th teacher to to join during the school year was going to teach today. Our desks were these old school wooden benches with 3 people sitting on each. Two of my desk mates decided that this new teacher might not last too long, let's just put our heads down and pretend we are unwell. I was still on the edge wether to do it or not. When the teacher entered the class, as is the norm, I stood up to greet her good afternoon but one of my desk mates still pretended to be unwell and sleep. While we were standing to greet the teacher approaches our desk which was at the very back of the class to ask me what's wrong with my desk mate. I said "she asked me to tell you she's pretending to sleep and being unwell" (it wasnt as direct as this but a little wordplay in my local language) a couple of people around me giggled and the tea her suppressed a smile and asked me to tell her, "tell her the tea her wants her to be awake" Next thing I know I've been slapped hard accross the face. I look up and it's our principal. I get slapped again and so trying to figure out what happened I say sorry repeatedly asking what happened. I get slapped some more times and got my hair pulled. The next thing I know I am being pushed out of the class and my bag thrown on me ...she asked me to leave the school - -all because she "thought" I was making fun of the new teacher
