I always agreed that if you went to a meeting with a headache or something you felt better after the meeting was over. They pinned it on the loving atmosphere and holy spirit. Wasn't until later I realized it had nothing to do with that. Instead it was the relief that the frickin meeting was over.
I know when I was out and family was in, they would be all smiles when they came home. Had to put on a false front. I can tell because they were a lot more chipper than when I was actually going to meetings.
