Actually getting in trouble for disagreeing with the teacher is nothing new.
When I was in 3rd grade, 1956 or so, I got a spanking, when the teacher told another student that he would get lead poisoning writing on his arm with a pencil, i.e. pencil lead.
When I told her pencil lead wasn’t really lead, but carbon like charcoal, she said I was wrong, I said no, you’re wrong.
That got me a spanking and 30 minutes standing in the corner. Then at the end of class, as we were leaving, she overhead me mumbling “She’s still wrong”, and I got another spanking.
I guess that was my version of Galileo’s “And yet it still moves.”
Unfortunately two spankings in one day was not my record. That would be three.
LOL
