My teacher kept us all in at lunch time but turned the temperature of the room up as hot as it would go why did she should I report her?

In this day and age, usually yes. But you decide. In the very late eighties. This cow of a teacher ms sh*t. Which she wasn’t anything close to being a teacher in my view. Made me a south East Asian, at primary school uk sit away from others in class. Right near the front by the chalkboard. Northwest area this was, scouse area. She didn’t even teach me or give me any work to do. I was on my own facing the wall for months and months. Films were played, while everyone watched. But I was not allowed. The whole class were white. This is discrimination. Everyone was given special treatment. I was yelled at many times, she would address me as ough!. If caning was allowed, I think it wouldn’t be wrong to think I would have been caned and not anyone else in the class. Karma will get to that stupid old ugly cow, or has it already. Ha ha ha!

I don't believe you.

Your class deserved it. If you report her, it is like biting the hand that fed you.

Your class needs to sober up. It is your class' fault, not the teacher.

You can report it, but be prepared. Every student will be called in an questioned about what happened and who made the comment.

How do you know everyone was sweltering, but don't know who made the comment?

If that's true then yes you should report it.  That's not teaching.
