As an ad-lib part of chairing, we have begun adding, "If you don't know what a sponsor is, we'll be glad to tell you and explain how to get one," and we always offer phone numbers to the newcomer.
Too often, I hear a lot of things left for the newcomer to puzzle out. I'm guilty of sharing on a step without pointing out how it eliminates my need to drink. A newcomer is there to stop drinking. Sharing without making reference to the drink problem, I think, leaves the newcomer wondering how, exactly, that experience applies to them.
Peace & Love,
