I get suspicious of any one in a dress on Sunday and Saturday. I go to thrift stores on the weekend and see them looking for cheap deals. In the religious section of the books, there are plenty of "old light" books and black bibles.
I can imagine those sisters where thinking, how someone just might come along and pick up that magazine, read it and come into the truth! They get to have a warm fuzzy feeling and hope they can be on the meeting with their wonderful experience.
