"Often, I'm spending months with a person in a very intimate context, getting to know the ins and outs of what they ate for breakfast, not to mention dredging up the most traumatic experiences of their lives, digging through their documents and photographs from difficult times, all of that. And that process, I think, can be extraordinarily strange for subjects who've never been interviewed before, especially if you don't acquaint them from the get-go with what you're trying to do, what it entails, and why you care."
