I have had this post stewing in the back of my mind for over a year. It's as though the various applicable pieces have arrived at various times and now I must figure out how to lay them out for your understanding. But perhaps you will understand, even if I just give you the pieces instead of trying to string them together.
Years ago, I worked with a couple kids fresh out of high school, neither religious, in a predominantly Mormon city. I often worked near them and we'd talk, and joke, and were friends as far as I was concerned, and as far as they were, too, I believe. But I was obviously Mormon which contained all their suppositions as ones who were not.
One day I came in to work and the girl told me she had just started studying palmistry. She wanted to look at my palm, because, according to her, the distance between the two main lines indicates 'open vs closed mindedness'. The wider, the more open, the closer, the more closed. She was certain that because I was clearly Mormon, there would be almost no space between the lines on my palms. So I showed her and she compared to her own, and her friend's hand as well. They were both a bit dumb-founded to find my lines were wider apart than either of theirs.
