If you're doing an interview you need conversational tension. After you talk to them you're not going to have a relationship with them they're not going to like you they're not going to be your friend.
I know it may seem surprising to people but learning dialog that has a conversational flow to it is not that difficult.
It's not an accident that both my sister and I are writers. Our parents created an accidental Petri dish. My family has great storytellers and I grew up in a very funny conversational house and didn't have television. This small family farm was a bubble world that didn't have much to do with reality.
Talking with you is sort of the conversational equivalent of an out of body experience.
