I was under the impression that AA rooms were a place where alcoholics could come in and share their experiences and feelings openly and freely without the fear of persecution that they would find out in the real world because everyone else in the room has been exactly where they're at, and even if they haven't been, they understand that they could one day..
If someone feels confident and they want to share that, they should be able to do that. And if they feel humbled, maybe that is somewhere they needed to go. This was a part of that individual's recovery journey. Everyone is going to do this differently.
