Being a spectator doesn't enlighten you
All too often those holier-than-thou backpackers who finally do come back from "roughing it" amongst people in their actual homelands, return with an unfounded sense of enlightenment that is unbearably annoying to their less worldly friends, family, and acquaintances. Newsflash: being a spectator in a third world country for a while doesn't make you less of an entitled asshole.
