Well, in my al-anon group, I would have been thrilled if someone volunteered to speak.
But Al-Anon and AA are different. In my AA meeting, I believe there were some loose guidelines about when someone should be a speaker, like x amount of days sober.
I don’t know if where the potential speaker is in step work is or should be a factor.
Does your meeting have a monthly business or group conscience meeting?
Perhaps the members there could help.
