I was brought up Quaker (now catholic). In their meetings for worship, if one is "moved to speak", if one has felt the spirit move them in a particular meeting for worship, one might share it. I use that kind of thinking as my guide in AA. In fact I see many similarities in an open discussion AA meeting and the Friends Meeting for Worship, there are important differences, of course.
If I feel something inside me, move me, in response to someone's own ESH that is shared, and it resonates with my own ESH, I raise my hand. Sometimes I am not always happy with my share, but if it came from the heart, or the spirit, I'm not shamed or embarrassed.
I also very much appreciate moments of silence in a meeting (like the Friends), sometimes the spirit is present most strongly in what is not said
.
Like Robby said, share your own special and unique ESH, it is important and may be just exactly what someone needs to hear... it is, ultimately not up to us to judge ourselves or others, it's His.
