And you've listed some of the myriad of reasons why people in society have built up hostility and impatience with others. There's literally no reason for the Lexus driver to park as they did, with visibly 6 other spots. So absent a good reason, at best it's thoughtless and oblivious. At worst it's an irrational mental ailment or on purpose to be a jackwad.
All of this, and so much more, inconsiderate selfish behavior is the unraveling of the fabric of our society. We are no longer considerate, polite thoughtful fellow people. We, as a whole, have become totally self-obsessed inconsiderate oblivious jerks who disrespect the wishes of others - at times on purpose.
The other day I was going 75-80mph on the interstate, passing a series of Semi Trucks traveling around 70mph. I was diligently passing, not squatting in the left lane. A car zips up on my ***, 1 car length away. At 75mph. Not only extremely unsafe, but extremely rude. Why do people behave this way?
It's not the end of the world, but it is just one of billions of examples of a very unhealthy mental illness in society. And in the aggregate it's why seemingly everyone is so short and rude in society.
