Personally, I think this whole "exactly" business STINKS. How can a meeting be EXACTLY on time, when people want to speak. Are you going to tell them to SHUT UP, basically like SHE did?? This is terrible, and it is UNLIKE ANY other meeting I have EVER been in, and I've been in many many meetings in my 19 years of sobriety.
Your group needs to have a group conscience to change these activities, and see if the group wants to keep it the same or change it. The group CAN change this, if by VOTE the majority wants change. If they all want to keep it the same, then so be it. But have a group conscience -- it's allowed by the Rules of AA. Every meeting I've been to has gone overtime, so allow EVERYONE to speak as long as they need to. It never goes TOO far overtime because we DO point out the time when we get close to closing. But everyone gets to talk when they need.
This sponsor of yours was TOTALLY OUT OF LINE. She should NOT have spoken out of turn. And this "time" thing has got to go! God bless and I hope things get changed around. God bless & please take care. Hugs, Lee
