Oh, boy. Did I learn that the hard way. At evening church a couple of years ago, I saw a girl who had been a member maybe five years earlier. A group of us were talking about something or other related to age and the girl looked at me and said, "How old do you think I am, Christian?" My brain told me to disengage, but I steam-rolled straight ahead. "27?", I said. A look of horror came over her. "27? 27? I'm 23 years old!" I wanted the ground to swallow me up in my embarrassment. "Oh, crap". She wasn't amused. Either was I. Lesson learned: Don't ever guess a woman's age.
