One of the patients I saw today was an elderly woman. She said she was referred by her daughter whom I had seen the week before. Apparently, her daughter was satisfied with the service we provided in our clinic and thus referred her mother to me. The mother mentioned later that her daughter was a doctor. Today, I am very grateful for that vote of confidence that doctor gave me. She did not identify herself as a doctor when I saw her. But sending her mom to me was a sign that I had done her some good.
