No, I’m not stretching. Take a good look at why these resignations happened and you’ll see resigning due to old age/infirmity is a novelty.
We can expect this to be a regular occurrence now though.
So, if I find a case or two of resignation due to old age or infirmity, what new condition will you insist on?
As I said earlier, one non-traditional act doesn’t justify the statement that a person does not follow tradition.
