Chris Harvey at Charvey in Vietnam reminds us of the secret to successful life anywhere, but especially while living in a different country and culture than one's home town. It seems obvious but we too often forget that our own attitudes toward people reflect back to us in how those folks respond to us. His Aunt Jackie had the best comment with the universal truth to " Treat others the way you wish to be treated." This is an important reading for all of us living as expats in countries like Viẹt Nam.
Over the past ten months here in TP. Hồ Chí Minh, I have been surprised how laid back I have become about what would be perceived in San Francisco immediately as rude behavior. It isn't really rude behavior or arrogance. There are just so many more people here in constricted space, so someone is more likely to cross you in unexpected ways. But I rarely see bad intent in those actions -- more likely it is not paying attention, and we all suffer that at times.
The Golden Rule works both ways. I am sure my change in response is a reflection of the general friendliness and "live and let-live" philosophy of Vietnamese people around me.
