Read the scenario of a formal one-on-one discussion. Sarah and Aidan are discussing fundraising for a school club. SARAH: In the past, we have successfully held different types of fundraisers. From bake sales, we raised about $1,000. From car washes, we raised about $1,500. AIDAN: Is there a cost difference in having either kind of fundraiser? SARAH: Oh, that's a good question. I had not thought of analyzing the cost difference. I'm sorry about that. AIDAN: You have nothing to be sorry about. The information you have here is great. We can make a note to analyze the cost difference the next time we meet. Which appropriate behavior does Aidan display? He is helping Sarah stay on task. He is being considerate to Sarah. He is collaborating with Sarah on the agenda. He is encouraging Sarah to contribute.
