I mentioned to my GP that i had met Fabio back in the late 80's? It became a running joke between us for the next 30 years. He would even call me at home to give me my test results and say, "una, this is Fabio." He would tell his nurses, this patient met Fabio. I dont think they were even old enough to know who he is.

I think there is a place on the chart to note "personal anecdote". How else could they remember?
