A week ago (a day in August 2014), a patient, Gina, came into my clinic. She told me she had consulted me already before. I right away made an apology that I could not remember her anymore. She then showed me a calling card which I gave her in 2004. She said she had kept it in her dresser for the past 10 years and she made sure it does not get lost. I was so happy with what transpired (seeing the 2004 calling card; what she did to safe keep it; and returning to me for a medical consultation). After I gave her a 2014 calling card, she said she would still keep the 2004 card as it is not yet worn-out. The contents are still clear. I was delighted with this encounter with Gina that I decided to document it.
I have recorded a similar enjoyable moment before in 2012. See link before.
