It's crazy when you realize, "oh, shit, they're just people." I don't mean it in an insulting way. I had that experience, too. Travel certainly helps. It's not even necessarily that you don't believe that before, just maybe that you didn't know or hadn't even thought about it, because who can know everything. But then what was previously vague/unfamiliar words in sporadic headlines in the background is suddenly very real and personal, standing in front of you. It's a gut punch.
