It amazes me sometimes how when you travel to different cities in America, there are some subtle cultural differences and mannerisms from city to city. Like how the vibe and mannerisms in New York City can be different from Atlanta. Or how people act a little different in Boston compared to Phoenix, Arizona.

Even in other countries, there will be difference between Tokyo and Osaka, Japan. Or you will notice a difference between the mannerisms of the people in London and Paris.

That being said, deep inside people are basically the same everywhere. People may act different socially but if you get to know people in one city and other people in another city, after a while, you may realize that they and we are all the same. The mannerisms and cultural differences are superficial. People are basically the same people everywhere you go once you start to know them a little better.

Interesting observation, but London and Manchester, say, might be a more appropriate comparison than London and Paris   

Good point

It is an interesting idea though. I'm from London myself but I've spent time in a couple of US cities - one on the west coast, one on the east. I can't put my finger on it, but each one had a distinct atmosphere. Culturally, I felt a lot more at home in the east coast city - generally speaking, the outlook and attitudes or people I encountered was closer to what I'm used to in London. In the west coast city, there seemed to be a kind of extreme politeness from people in the service industry that for a cynical Brit like me, came off as insincere and falsely upbeat. But maybe they really just are that happy and caring!

Good observation. I think in some of the cities in the western part of the USA and especially in the rural areas, it's just more relaxed compared to a northern east coast cities like New York or Philadelphia. Strangers will be more open. But a stranger in New York will be more reserved. And even in different sections of New York, people will be slightly different. Brooklyn tends to be more relaxed and friendly compared to Manhattan.

I used to hang out a lot in New York and Philadelphia so it's easy for me to see the difference out west. One observation is that drivers tend to get more angry and aggressive in the major north east cities. But drivers out west and even in the south tend to be more forgiving and yielding even if the traffic is terrible.

I also notice that that in places like in Arizona, people publiclly tend to be more calm and cheerful compared to other places where people will be polite but not show much cheerfulness and be more reserved.

Also temperature tolerances can be different too. Many people who live in Los Angeles think 50 degrees Fahrenheit (10 celsius) is too cold and uncomfortable so they will wear a substantial jacket but to many people who live in winter climates, 50 degrees is not bad and some people will wear shorts.

Of course, these are just generalizations.

A more pessimistic person would say that humans everywhere suck about the same. We all have conniving little monkey brains that just want to keep all the other little conniving monkeys from stealing our food and stealing our mates, so we bare our teeth, beat our chests and throw our feces everywhere...
