You can't leave us hang like that.
Well..........we're waiting!
OK, here are a few . . . remember, this WAS only 4th grade, so don't expect anything TOO extreme . . .
First off, this nun hated boys - anything, and I mean ANYTHING that happened, she'd punish the boys. This of course was a WONDERFUL opportunity for 4th grade girls, who
did know how to make things like paper airplanes, after all. So one time she kept all the guys after school and led the girls out . . . sitting there steaming, I decided this was <expletive> so I got up and walked out. Fully expecting to be chewed out the next morning, I went in with some apprehension, and . . . nothing. Next time it happened, a few more of the guys walked out with me. She quit keeping the guys after class.
One time when report cards were being handed out, it was the Monsignor of the church who came in to hand them out and critique our performance; he'd review our report cards and offer stern advice. When he asked me why I didn't try harder, I told him if I don't try at all I get a bad grade, and if I try really,
really hard, Sister tells me I cheated and get a worse grade . . . so I just try medium. The nun was right there and told him that wasn't so and I was just lazy . . . so I looked at her, looked at him, and said "Monsignor, that's what they call bearing false witness - just ask anyone in the class" Surprised that I called the nun a liar, he saw a bunch of other students nodding, so he just handed me my report card and said "Next!"
At one point I had a broken wrist, cast from just below my elbow down to my finger tips - I could only write by wedging a pencil into my cast. During a parent/teacher meeting, this nun just kept telling my mother "He has to improve his handwriting." (That much was true, my handwriting was - and is - nothing to brag about. But while I'm wearing a cast?!?!) Mother was upset and had a little heart-to-heart with the principal, who was also a nun. (A good one, by the way.)
And once, angry at the whole class, she proclaimed "Anyone that doesn't like this class is free to go across the hall to the other 4th grade class!" When I stood up and started to leave, she told me I couldn't - so I pointed my little 4th-grade finger at her and said "Then YOU LIED, Sister! That's a SIN before God!" (one of her favorite lines) and her response was something along the lines of "Shut up and sit down." (I got that a lot.)
One day, my Dad gave me an "Enicar" stopwatch, which I proudly wore to school one day. The nun saw it and asked "Does your father know you have that?" I told her Dad GAVE it to me. She asked to see it . . . I showed her my wrist . . . she told me to hand it over . . . I told her she could see it fine on my wrist . . . she DEMANDED I hand it over . . . I informed her that she may get away with stealing combs, pencils, and erasers from other kids, but she was NOT going to steal this watch. She scolded me and walked away. (I was fully prepared to punch her in the nose with my little 4th grade fist if she made a grab for the watch . . . and I suspect she knew it, and could look further ahead to unpleasant consequences for her if she provoked it by trying to take the watch.)
There are more incidents in a similar vein (like the time I took the 5th, after Dad explained what I'd heard on an episode of Perry Mason the night before) but I wasn't the only kid having problems with her, and several years later I found out - from one of the good nuns - that she wasn't well regarded by the other nuns, either. Which is why she was ultimately invited to leave.
