I remember 23 in the O.P.
Also, when I started grade 1 in 1968, we had a roll call where the teacher would call out your name and you had to say ''Present'' not ''Here'' or ''Yep'' or ''Yo''.
Then, we recited The Lord's Prayer followed by the National Anthem.
No exceptions. Everyone had to do it.
And the teacher had the ''strap'' sitting on the right corner of her desk and wasn't afraid to use it.
If anyone disrupted class or talked back, you got the strap and then were sent to the Principal's office.
If the matter was severe enough, he then contacted your parents who came and picked you up and you were sent home for the day and made to apologize to the teacher in front of the whole class the next morning.
That taught you manners and discipline.
And this was just regular school, not a private or Catholic school.
Boy, times have sure changed.....
