In the beginning I told almost no one because of my many failed attempts. As time went on most of my friends were in the program and of course knew.
In the last 25 years I might tell anyone and at times it surprises me how many others are, as I live in a tourist area with many visitors who sometimes want info where the meetings are.
Obviously it’s a personal choice.
On the other hand if your in AA it might be a good idea to withhold this info from outside family members because we may be watched by some who need recovery. If we relapse they many thing “see it doesn’t work.”
