It's been nice, actually, to keep in touch with a lot of the people and families that I've written about. Like with the kids I was just writing about from Guatemala, who survived being kidnapped and fleeing violence, it was nice to just sit down in their living room and play bingo with them, go to dinner with the family. And sometimes not thinking about it in such a mechanistic "I am now coming to report and get what I need" way, but just spending time, helps you see a more natural version of who they are too.

I think most of us, as writers, have had experiences where you get edited and it doesn't feel like your voice at all. And so it's been nice to go through the experience of having a lot wind up on the cutting-room floor, and yet still feel that your voice is being - not purified, but made more yourself. I think that's a very rare thing.

I think when I was doing my very first interviews, I probably brought a notepad and did ask people my first fifteen questions while sitting in a Starbucks or something horrible like that. And I found that, oftentimes, the most important thing at the very first interview is just establishing a personal connection and developing some sort of rapport so that I can go back to them again, and then maybe again, and maybe again after that.

One thing I've discovered is that if you remain in contact with people, if you build longitudinal relationships, if you invest in sources who seem at first like they're uncomfortable or unwilling to talk, if you keep in touch with them, a year later that might yield something much more powerful.

The tremendous challenge of narrative journalism about subjects that are underreported is, how do you make people care about something they think they already know about, or think they don't need to know about?

There is space for a different kind of investigative reporting that's about immersion and obsessive attention to detail and deep listening.

Often, my central challenge is figuring out how do I build trust, how do I acquaint people who've just endured some terrible event - losing their child to murder, say, or being sexually assaulted - with the bizarre and sometimes invasive nature of in-depth interviews that aren't just a quick list of ten questions?
