Dear Grapevine

HOW RIGID do we need to be? I've been sober for six years. At my home group, everything is going smoothly. Once in a while, though, an old-timer will bring up something that I don't understand. After all the meetings in my area, at the end of the Lord's Prayer, we say, "keep coming back, it works." All of a sudden, they want to just end it with "amen" because they think the phrase comes from rehabs. But I like being reminded to keep coming back.
