I absolutely hated school (late 70s to early 90s) because I:
-Developed a stammer aged 13-16, so reading aloud in class was an absolute nightmare, and the teacher would scream at me for "being lazy, not paying attention" when in fact I simply couldn't get the words to leave my mouth. I was an excellent, A-grade student, and very well-behaved. I just literally had a stammer, which I lost soon after school and when I had started at university.
-Couldn't swim, yet was always pushed into the deep end by our swimming teacher when we were taken to baths every week. I found this terrifying. Every week, for years.
-Back then they would mix years, so I was in the 3rd year of primary school (in old money - I think that's year 5 now?) and we shared with the 4th year (year 6). The teacher was immensely aggressive and just never believed I was 3rd year, and for some strange reason kept insisting I was in the 4th year too. So, he would regularly make me come up to the front, rip up my work right in my face/the whole class, screaming "DO BETTER!" Thinking about him now, it was very traumatic. He was like this with everyone.
And yet I STILL went to school. A day off was absolutely unheard of. The only days I can remember having off was when I had chicken pox aged 8.
The way we were treated - and this wasn't especially unusual for the decade we were in - is the sort of thing which you would now see reported in the news. It would NEVER be allowed today. And yet, we went in, day after day.
