David Marchese is the interviewer for New York's "In Conversation" series.

"The thing I like about doing long interviews with people is that each one feels like a totally unique experience to me. It’s not like I go into an interview and already know the arc of the story I’m going to tell, and I’m going to just fill that in the best I can. I have ideas of what to talk about and what the conversation might entail, but it does feel like I’m starting at zero and the conversation can go anywhere.”

Boy

On the nature of violence.

When my brother was twelve, I found six mice nailed to the wall of the abandoned tree house in the woods near our apartment. He spent a lot of time there. It seemed to me the little mouse faces were frozen in agony. As though they’d been alive when he’d hammered the nails through them.
