Sometime in the early 1990s I was treating a woman in an intensive chemical dependency gro

up. Let s call her "Grace." Grace was a flight attendant and had been suspended from her job with a major airline due to her untreated alcoholism. After the eight week program, I suggested to her it might be a good idea to solidify her foundation in recovery before returning to work as she would be working in a high - risk environment (serving alcohol, being out of town alone, etc.). Grace, however, returned to work shortly after completing treatment. One day while she was departing from a plane at the end of long day a major craving for alcohol overpowered her. There she was, in the Los Angeles International Airport pulling her roller-bag behind her when this massive craving to drink came over her. She tried to just "think through it," or "just forget about it," but it was way too powerful. It was so powerful, in fact, that she had resigned to herself that she would just go drink. On her way to the bar in the airport, Grace had a moment of sanity. She stopped, picked up the airport paging phone and said, "Will you please page friends of Bill W.," she paused, quickly looking around for an empty gate, "to come to Gate 12？" Within minutes, over the paging system in the LA International Airport came, " Will friends of Bill W. please come to Gate 12." Most people in recovery know that asking if you are a friend of Bill W. is an anonymous way to identify yourself as a member of AA. In less than five minutes there were about fifteen people at that gate from all over the world. That brought tears of amazement, relief and joy to Grace. They had a little meeting there in that empty gate, total strangers prior to that moment. Grace discovered that two of those people had gotten out of their boarding lines and missed their flights to answer that call for help. They had remembered what they had seen on many walls of meeting rooms: "When anyone, anywhere reaches out their hand for help, I want the hand of AA to be there and for that I am responsible." Grace did not drink that day. I would venture to guess that none of the people who came to Gate 12 drank that day either.
