The Nepalese are extremely friendly, and I don't regret going, I just walked away with different feelings. For me it's not about guilt, it's about the shock of being part of a global economy that is at its core exploitative. That I live comfortably while these people don't have basic medical care, and my little splurges are equal to a days wage for them. Basically it was a window into the incredible, and unnecessary, inequality that exists. Something that didn't really hit me fully until I experienced it first hand.
