"Everyone I know, it seems, wants to go to Africa, wants to volunteer for a few days in an AIDS clinic or an orphanage. And that's good. It's a good impulse. I encourage them to go... but inside myself I whisper to them: 'Be careful' - you will be haunted by what you find there, and you won't be able to wash away what you've seen and heard. You will see things and hear things, and then you will be responsible for them, for telling the truth about who you are and who you discover you are not, and for finding a way to make it right. That's why actually getting on a plane and going there is dangerous and very important. Because once you see something, you can't un-see it."
