IIRC, most of mine were pants down, as were other kids. Then I’d catch #e!! at home and get worse. I remember one teacher had been on the Bataan Death March and my dad was a retired Marine Gunnery Sergeant. Think about how red my @$$ was at the end of that...
I grew up in Texas schools in the days when spanking in the principal’s office was done, and NO ONE’S pants were pulled down.
My Jr. High math teacher (also Asst. Principal) was a retired Marine officer. Guy was over six feet tall. Never saw him spank anyone, he didn’t have to. The intimidation was more than enough.
No one has a right to pull a kids pants down for a spanking especially in public.
