Oh well now you are talking Los Angeles and that is a whole different world over there.
In fact visit in San Diego and you will find the people are quite a bit different. I'm from Northern California; I grew up in the Bay Area. Just as with New York there are certain areas that the same ethnic group of people live in. For example in Fremont CA there is a large population of people from India.
I just hope you don't let Los Angeles speak for all of the West Coast.
Because the Bay Area and Northern California is way different then Los Angeles.
People in Northern California are more direct then you realize. We have to get you down here for a visit.
I think the smog has effected the people of LA in some strange way.
