Not so much in that we have the best parties and talk to "Like, OMG, everyone giggle giggle," but in that we can move people away from the issue at hand, take them away from the group one by one, tease the problem out, use communication on a more personal note to share understanding and thus create harmony.
I find a lot of friends will come to me if they are having an issue within a group dynamic- they will talk about problems. I will relate to the problem in terms of other scenarios, use comparation. Most importantly, I will show them that they are not alone, that whatever the issue is, there is an empathic understanding from me through conversation and a new perspective might make them see the issue in a completely different way.
If there are people having misunderstandings between each other, I find they both come to me in their own time, divulge a large amount of emotional and personal information, and take away from the conversation a more open point of view that then allows each of them afterwards to talk together about the issue without so much defensiveness.
Does that make any sense? I feel like I might be rambling here.
