While traveling in Chile, I was told of anti-American sentiments. I do not doubt that such feelings exist, but I never experienced it first-hand. When I was asked (this usually occurred immediately), where do I come from? I never lied.
I had been told that those who smile at me, are just pretending to be nice. Perhaps this is so. But with the endless kindnesses I have been shown, including people going out of their way to assist me and befriend me, I have faith in their sincerity. Any prejudice that may have been, during these one to one encounters, seemingly dissolved.
