People unfamiliar with how society in NYC operates believe that there is no etiquette within the city limits. That cannot be further from the truth. There is an unspoken way to properly interact with the cityscape itself and the people that inhabit it. My friend Josh of QuePasaCabarete shared this piece from Nathan Pyle. He has decided to illustrate a lot of these unspoken rules. Nathan also has a book full of these tips and etiquette when in NYC. You really need to check it out and hopefully, you will learn something.
I just read this article and it addresses some very interesting aspects of societal life. It specifically speaks to the behavioral role of wealth in everyday people. It explains that through certain experiments, they were able to prove that the richer a person viewed him/herself to be, the more unethical they behaved. Interesting indeed. Give it a read, be you poor, rich, or trying to get rich.
