This was my thought, as well. At the risk of sounding...I don't know some 'ist' word, people are just raised differently and the world varies so much.
Picture you're on a beach, and behind you is a shirtless man with a machete. How you feel is completely dependent on where you are in the world. In LA, you'd run for cover. In south east Asia, it's Tuesday.
I learned a lot from my travels, to back the adage about traveling and learning. I remember being in a small fishing village and someone caught a large fish. I don't even remember what it was now, but the fisherman was so excited to catch this big valuable fish he shared it with everyone, even me the foreigner he'd never see again. Made me think about how selfish we as Americans can be. We already have a good life, and still look for ways to get ahead of everyone else. Yet a person with nothing is happy to share what little they'd found.
Story aside, I agree that the experience would vary wildly by country, or at least upbringing.
