Over the years I have found myself explaining to complete strangers again and again why I have come out to ask them why they are standing in my backyard.
The notion of private property is intimately related to frontal lobe function. More and more people in the modern world have trouble understanding the idea of trespass. This is normal in primitive tribal societies where nobody really has any property which is not regarded as communal. Modern people are increasingly anything but modern. They seem more and more primitive every day, lapsing back into barbarism. The reason it is noticeable is that it is deteriorating day by day, not decade by decade. It is happening quickly enough for an observant person to see the changes from month to month.
It is my humble opinion that most people in the current era display classic symptoms of frontal lobe damage.
Not as an exception. As the norm. People with frontal lobes working are definitely in the minority everywhere you look. You see them sometimes like albino squirrels ... as a rare anomaly.
