Back where I trained, he ran one of the country's top neurosurgery residencies. Before his retirement he was widely considered one of the best brain surgeons in the world, and people came from all over the planet to see him.
His position, and skill, brought him enormous financial rewards. Because of the size of his house he threw a large Christmas party every year to which all the neurology and neurosurgery people were invited, including peons like me and the other neurology residents.
He was also socially inept, and entertainment was never his thing. Obligated to host the party, he firmly planted himself by the door, greeting all who came with "Glad you could make it. Food is to your left, bar on the right." This was his mantra, repeated endlessly all evening until it was replaced with repetitions of "Thank you for coming. The valet is to your right."
For one night every year he was the highest paid doorman on Earth.
I went to his parties for 4 consecutive years. In that time I never once saw him leave the door (maybe he had a foley) and never heard him say anything there outside of those 2 phrases.
We all learn a lot from residency. Among other things, I learned I didn't want to be a doorman.
