Nothing in middle and upper school, but can remember my whole school witnessed ruler'ing from my first school like yesterday. Was a Pakistani girl in our school, proper wrong un, looking back, she knew she was like untouchable as placed in our school from elsewhere. Was playing in the playground with a couple other boys, when we got spayed with gravel, small stones from her. So we retaliated in kind with the same, it was seen, and the teacher somehow didn't see the initial cause by her. Anyway, it was rolled up into a big thing, despite others in the playground saying she was chucking stones at others prior, so 3 or us got 10 rulers to the open hands in front of the school. My Dad knew it was a kind of knew it was a "mis-trial" by the school, he told me I had been one half of it and caught, so take the punishment served (Ex-military Dad). Funnily enough, the girl after some time was off again to another school, she was just trouble, the mention of Pakistani was due the her being dropped into basically an nearly an all white school on the outskirts of Bradford, which played a part in the severity of our punishment, back then at that age, I didn't know any different, but looking back my parents did.
