There is not a clear-cut management parallel in this post. Punishment and abuse of children are in the news lately, and this is a completely different, but related slant on the issue.
Recently I was in a supermarket, rolling cart peacefully down the frozen food aisle when I witnessed something disturbing.
A young mother was pushing a cart full of groceries with her son in the seat of the cart, facing her. Evidently, the young man either took exception to something she decided to buy or to something he wanted and she decided not to buy.
As I walked near them, he started to beat her.
