TL;DR
- The author and his high school classmate, Jimmy Tremarelli, maintained a years-long inside joke of addressing each other as 'Doctor'.
- The author has adopted a similar long-term habit of referring to Sainsbury's as 'Saino's', which is not appreciated by his wife or others.
- He fears that his commitment to the 'bit' has made him the irritating person he used to mock.
- The author discovered Jimmy Tremarelli is now a teacher at their former high school.
- The author speculates on the potential for humor in the continuation of their old joke if they were to meet again.
