You sound like you know people who were close to those in "The Life." Your correct, it's not like (most) Hollywood films that focus on the "honor" part. There isn't honor among those who are psychopaths. I saw an interview with a former cop who said Goodfellas was probably the most realistic portrayal of mob life.
Did your mom every get to go back to Sicily to visit? It is a beautiful place. When I was returning from the horrible hell hole that is most of the Islamic Middle East, going back to a place like Sicily or other parts of Europe was like breathing again after holding your breath. I hated the Muslim nations. Even the rich ones like Bahrain, UAE, and Saudi had this dark, almost spiritually dark, presence. It's hard to describe.
I lived in Europe later in my career with my family (Germany). When our kids were young, my wife and I took them to Rome, Milan, and Florence. I was in awe of the architecture, the history, and the art. There I was, starring at the Statue of David, and my little ones were tugging at my sleeves, whining that they wanted to go back to the hotel to go swimming.
I got to Venice as well (my wife was not with me), and fell in love with the place. One time in Sicily, me and buddy rented a car and drove to the top of Mount Etna. They sell a liquor there called "Etna Fire Water."
You cannot imagine how potent this stuff is. Pour it on a house, and the whole thing would go up in flames.
Take care my friend! And thanks.
