It's a New York state of mind, born of severe overcrowding. Those who talk too much are immediately sidelined as a loser. There are no exceptions. The only way to achieve some kind of inner peace is to screen out conversations.
The classic example of that is the ethos on the commuter line of Metro-North railroad. The protocol is to limit conversation to functional talk, as in, "Wait one minute, I will find my monthly pass," when the conductor comes for tickets. Anyone unware of this social norm or dares violate is shunned or made fun of in the devastating way New Yorkers can unleash scorn.
One evening as we work warriors boarded the Metro-North for the ride back to Connecticut, a drunk bumped up against a Wall Street type. "They don't have a bar car on this train, " he bellowed. Not missing a beat, the investment banker indicated he felt his pain,"They shouldn't have eliminated prayer in schools." Confused, yet knowing he had been put down, the drunk collapsed into his seat, heard from no more.
