In this case, the girl is a good student and not a trouble maker. However, letting someone copy her work deserves that she understand this is a serious offense. If she did that in college, she risks being kicked out. She should be sent to the alternative school for those few days as the original punishment was. Never again would she make that mistake.
I recall a lab test in Biology in college. A student kept following me around, trying to copy my work. I finally went to the professor to report this so I wouldn't be suspected of helping this student cheat. I didn't want to risk being expelled from college.
The issue is not the spanking but that a male spanked a teen girl in violation of the school policy the assistant principal should have known.
You don’t want perverts getting their jollies seeing teen girl’s behinds.
It’s just not appropriate even for an innocent spanking, as I am sure he is not one of those perverts. But, it’s only appropriate to have the same gender doing the spanking.
Alternative school is so that good kids who did something wrong can get training in how to be bad from the professional punks.
