I didn't listen to the whole vid. But, this one sounded like this teacher was troubled by the fact that these girls were spreading their legs and showing their panties.

Teenage girls can be nasty.

I substitute taught and the teacher I subbed for had all the girls sitting in the back of the classroom because their butts were hanging out of their pants and their thongs were showing and the teacher didn't want the boys to get distracted.

My question was why didn't the school make those girls wear decent clothing to school. They had a no belly shirt rule but didn't enforce it.

I suggested that they get some really ugly smocks and put them on every single girl that wasn't dressed appropriately and it would probably be the last time they wore their belly shirts to school.

People laughed at me but I wasn't joking. 😊
