I've seen Mr. R., a 51 year old, three times for medical visits.
The first two visits were for acute problems.
The third was for a full history and physical.
He's always worn all white (a white shirt, white pants, white belt, white socks, and white shoes).
Finally, on our third encounter, I had time to ask the obvious:
Me: I've noticed you always wear white (I figured he would be impressed by my astute skills of observation).
Mr. R.: Almost ten years ago my daughter was diagnosed with leukemia. I prayed and asked GOD to cure her. I also vowed to wear white for the rest of my life, as long as she was still alive. She's still doing well.
Me: That's great news. Thanks for filling me in (I had no idea his reason for wearing white would be so impressive).
