As a reader, you can help the group quite a bit by not apologizing prior to reading and by not interrupting people while they re reporting to you. Just read, then write down what people tell you. An apology is a plea for people not to hurt you. Your listeners are already worried that they ll do just that. If you show them your naked heart ready to bleed, they won t tell you very much about your paper for fear they ll hurt you more.
Interruptions have the same effect.
Either you seem defensive and combative or you seem defenseless and afraid. As a responder, you need to keep trying to track your reactions moment by moment so you can do more than merely summarize at the end. Just jot down key words, phrases, or questions trusting that you will later recall how you were feeling at that moment. Don t abbreviate your own response because someone ahead of you had some of the same reactions. The writer needs to know how widespread the reactions were.
