Anyway... seated right next to me was a woman I used to talk to regularly at my Sunday morning AA meeting!! Hmmm... she was drinking, and.... she did not acknowledge me.
Get used to it bro. Not everyone stays. She may have been someone who was just questioning whether or not she was an alcoholic or not. I know many here have heard people in meetings say that a normal drinker wouldn't question that but that is nonsense. It may have just been simple social embarrassment for her, of course she may be an alcoholic and you upset her evening of drinking. In that case, good on you!
