You know, way, way, way back in the olden days we had a bus driver, Mrs. Lou that you never ever crossed.
She loved us all dearly, but if you stepped out of line she had no problem pulling that bus over and busting your butt for you. And yes I mean literally bending you over her knee and whaling the tar out of you. Didn't matter if you were in kindergarten or a senior in high school.
On the other hand, if a kid got on the bus all black and blue and she thought it was happening at home, she was all over the situation. More than one kid went home with her for a few days when something bad was brewing.
She was my driver for all 12 years and I cried at her funeral years later, and I wasn't the only one of her 'kids' there.
The parents of those 'precious darlings' should be ashamed not only of their kids but of themselves. The kids are generally an adequate replay of what they see at home, you know?
