I had 3 older than me. I don’t know what it was - but my first grade Sr.Concepta was truly the best. And my two schoolmates that are still my friends today - did not like her and afraid of her. She did reprimand one of them - and I think fear was instilled then and then no more likie of Sr. C. But we were all in agreement of our 2nd grade nun - YIKES - flying down the aisle with the veil flying in the wind. You stopped breathing at that point.
I never got the dreaded circle on the blackboard treatment. She would draw a little circle that you had to press your nose against, and it was just high enough to have to be on tiptoes.
One boy spent a lot of time under her desk.
Pencil sharpening day was traumatic for some. We would stand in line by rows up front and QUIETLY sharpen our pencils with the manual crank sharpener. Woe to the child who had teeth marks on his pencil. She could spot them with her peripheral vision at 12 paces. The offending pencil would be held aloft and the child chastized publically while everyone else froze and a couple of kids still in line turned green or wet their pants.
You know, I don't want anyone to think I am bitter. Even quite satisfied "survivors" of catholic school during the 60's love to swap war stories. I think there are even books.
