Change in location, change in psychology of people?

They say people change with time, but do people change with location, too? Maybe yes, maybe no, maybe its just another reversible psychological change. I am an Indian who went to the United States for spending two quality years in Grad school, and now I am back to my home country. Here are a few changes I noticed appear in people when they relocate from India to the US and vice versa.

From India to the US:

1. Exaggerating the use of Thank you's and Sorry's and Excuse me's.
2. Following traffic rules blindly (except for speeding when no cops are around).
3. Ignoring/accepting public display of affection.
4. Driving used sedans, and dreaming of owning a Porsche!
5. Regarding family back home as the most important thing in life.

From the US to India:

1. Mentally converting Rupees to Dollars during every single financial transaction.
2. Complaining about the roads, traffic, population, pollution, etc.
3. Savoring every bit of junk food sold on the road-side stalls while complaining about food in the US.
4. Catching up with old friends, but secretly missing friends and the lifestyle back in the US.
5. Moving around with a 'I have lived in the US' air but secretly feeling proud to be back to one's own soil.

Oh, and this hub does not intend to offend anyone. Psychological changes vary from person to person, and not everyone may relate to the points above. It is just for a good laugh!
