This happened to me once. I was Year 5, so I'd have been 10. I was always well-behaved and hard-working at school, had never been told off until this point.
I can still remember exactly how it happened.
We'd done some handwriting practice, and our teacher was a real stickler for presentation, and on that occasion, I'd forgotten to write the date in my book.
When she marked it, she wrote "Date?" where I'd forgotten to write it. And somehow, my brain decided, "that looks messy, I'll cross it out." So I scribbled through her comment and thought no more about it.
A couple of days later, just after lunch, she calls me up to her desk and begins screaming in my face. I was HORRIFIED. I remember just looking out of the window over her shoulder as she continues to yell at me. When she finally finished yelling, she sent me back to my table, and I gave a sort of relieved, anxious smile at a sympathetic-looking friend, and she began to yell some more!
In hindsight, I realised what I did was pretty rude - I'm a primary school teacher myself now, and would certainly tell off a pupil of mine if they did the same - but I've never thought it justified the screaming-at that I got.
This event was nearly 30 years ago now, and I still remember it like it was yesterday. I'm a bit of a grudge holder, always have been, and never liked her from that moment on. I've never been good at hiding my opinions, so I suspect she knew, and then didn't like me either.
I know for a fact that she told my mum at parents evening, and my future Year 6 teacher that I was rude and ill-mannered. Fortunately, my parents chalked it up as a mis-match of personalities, as I'd NEVER had a teacher say a bad word against me until that point, and my Year 6 teacher seemed to make a point to get his own opinion of me, which I was always grateful for, and I really liked him. If anyone knows a Dave Allen, primary school teacher, who'd be about 58 now (he turned 30 the year he taught us), he was my favourite teacher!
