I was indulging in an age-old female tradition the other day—getting my nails done—when I overheard two older women strike up a conversation at the dryer. I listened with fascination as they circled each other, looking for that commonality that would allow them to have a meaningful exchange. One had children, the other didn’t. Strike one. One went to First Baptist, the other attended First Presbyterian. Strike two. They’d both discovered the nail salon about a month ago, and agreed it was one of the best they’d been to. And then came the home run: “Well, what did you do for work?”
