The absence of rules, regulations or "musts" is one of the unique features of A.A. as a local group and as a worldwide Fellowship. There are no bylaws that say a member has to attend a certain number of meetings within a given period. Understandably, most groups have an unwritten tradition that anyone who is still drinking, and boisterous enough to disturb a meeting, may be asked to leave; the same person will be welcomed back at any time when not likely to disrupt a meeting. Meanwhile, members of the group will do their best to help bring sobriety to the person if there is a sincere desire to stop drinking.
