I had one teacher who was my year 5 form tutor who enjoyed humiliating me and it seemed to be a game.
I looked her up and she's one of the only teachers who still teaches at that school.
I was dyslexic and really struggled with following instructions. I was bottom of my class and she missed no opportunity to remind me.
Once a year the year 5 students would get to go and use the labs in the big schools. We were all very excited.
The lab teacher and my form tutor were in the lab with me and instead of putting the liquid solution in a test-tube I put it in a tray.
My form tutor screamed at me "no no no no no!"
I was so embarrassed. She then made a big fuss of rolling her eyes and muttering under her breath as she corrected my mistake. "I knew it would be you who would get it all wrong"
There was another boy in my class who then made the same mistake 5 minutes later and he was approached kindly by my form tutor who triumphantly told him "don't worry George you're not the stupid one BessieBenjamin is the stupid one."
From that point onwards I wholeheartedly believed I was stupid and the other kids would bring it up.
I also wanted to hold a charity bake sales so I wrote a speech for the whole school to read out. It was my first speech and I was very nervous. That same teacher asked to see my speech as I was going into the assembly and shouted as loudly as possible in front of the whole assembly "this is all wrong, everything is wrong. Why do you always find these things so hard."
She then positioned herself in a place where all the kids could see as they filed into the assembly and would periodically say while aggressively scribbling on my notes "wrong, BessieBanjamin wrong again...NO Bessie Banjamin you cannot spell anything"
I was so embarrassed
It would have made zero difference to my speech to just let me be, I knew how to read my writing.
