I would prefer to do it on Skype or a telephone. Writing is a tool of distance; you think about your words and have the time and opportunity to structure sentences to say what you want them to say rather than have them hang baldly. I'm not accusing you of being dishonest when you write, but it's human nature to frame traumatic events in careful ways when given the opportunity. I want to hear you speak about them. That's a test of control in and out of itself.
