What’s the Date?

I had a doctor's appointment today. Everything was good, but then a young woman came in and asked questions for Medicare. One of them was, “What is today’s date?” My answer was, “Friday is the thirteenth; today is Wednesday, so today is the eleventh." Then she asked if I knew where I was. Then she asked if I knew who was president and who was president before that. I wonder if they have many patients who drive themselves in and don’t know where they are.
