The new priest tries this. The old priest suggests, "Try saying things like, 'I see,' 'yes,' 'go on,' 'I understand,' and 'how did you feel about that?'"
The new priest says those things, trying them out. The old priest says, "Now, don't you think that's a little better than saying, 'Whoa... What happened next?'"
