Then he'll either sober up by the time of the interview or will suffer from hangover, which won't help.
I guess it's best to concentrate at the interviewee as much as possible, as if you were talking with no camera at all. As a teacher I was very uncomfortable in front ofan audiencea class, and "pretending" I speak individually to particular students constantly switching from one to another helped me a lot better than drinking.
Sunday we're going to do a live news update instead of an interview but I think an interview might be easier because the focus wouldn't really be on me. The management hasn't really given us anyone to interview so I don't know what to do about that. People in comments sections can be nasty so I'm worried about that. I feel like saying they hired me as an editor not an anchor but I don't want to emphasize things I can't do since I just started working there a month ago.
