Mean 2nd Grade Teacher

So I was in 2nd grade of course as the title says I was in this class that I didn't like I didn't like the kids or the biased teacher I will never forget that teacher's name his name was mr.Mayfield and early in the yr my parents got into with him but he just didnt like me at all for some reason that I still don't know till this day but one during school we always talked as a class at the end of the day because he would let us and so we were talking low and not to loud to not disturb other classes so as we were talking we got graded in our folder Monday through Friday and I always had A's and B's so he called me up and he put a B in my folder and I was happy and excited so right before the bell was about to ring everyone started talking louder and was one of the lowest talkers and he pulled me out of everyone and pulled out my folder and changed my B to a D and long story short I got 2 spanking and after I told my parents even though I was crying so much and they had a talk with our school principal and got him fired
