But every once in awhile, an interaction initiated by a stranger has no underlying motive of self-interest, which conflicts with our traditional worldview. When this paradigm is challenged, we don't always know how to evaluate it with anything other than entrenched skepticism, which unfortunately, diminishes the true value of such kind acts simply for what they are - as I've found firsthand during my travels.
During my first day exploring Bangkok, I was walking toward a tourist area known as the Grand Palace by myself. Five minutes into my walk, I was stopped by a Thai man, asking my name, where I was from and generally engaging me in some friendly conversation. While on the inside, I was skeptical of the reason behind this interaction (due to tourist scams you read about), I wanted to remain polite, at least initially.
