stcyr, thanks, you pretty much said what I was going to say.
How people behave socially is a reflection on the values and quality of the society. If everyone only gives a shit about themselves then you obviously have an anarchy, even if it's only an anarchy of mores. The incident was not a big deal, but I think it was telling.
In my original post I did not mention what happened on the drive home. Another asshole in a hurry. Guess I was driving too slow (the speed limit) so he passed me on the shoulder on the right and probably hit 85 as he disappeared in a cloud of dust.
We also had this happen locally a few days ago with a car with 3 teenagers in it. The driver, a 16 year old girl, tried to pass on the shoulder on the right, lost control, hit a light pole, and slammed into a tree. Her girlfriend, who was riding in the back seat, was just taken off life support and died day before yesterday. The passenger is still in critical condition.
Everyone's in a hurry in our society, and there's a lot of rage in it too. Not good.
Now, as to Islamic terrorists and heart disease, we can solve these problems by building more McDonalds in the Middle East and removing the ones in this country. [;)]
