The perennial cynic about all the wrong things, aren’t you.
The lady was given a figurehead job. As if just having a grownup there would cause unruly kids to simmer down. That was when kids respected grownups. What was she empowered to do? Diddly squat. They hired her where she would prove to be a patsy, but old fashioned she had no idea that kids were this wild today and so accepted the post.
One should not accept a job that they cannot handle.
The lady could handle the job of being a bus monitor, not better than she could handle the job of being a brain surgeon.
