In a restaurant, I just heard a mother angrily call her son — about 6 years old — a “bastard” and threaten to take his dinner away from him. He was so obviously scared that it makes me wonder what things are like at home when outsiders aren’t watching. There was a father with them, but he didn’t say a word the whole time. Some people shouldn’t reproduce — and others can’t be trusted to raise children in loving and healthy ways. Those are the people who typically pass along their dysfunction to the next generation, and they often wonder why their children are so hostile and unhappy after the kids get old enough to understand what happened to them.
