Difficult to see him like that.
He is one of my favourite royals and somehow he did not change that much for the past two decades which gave the feeling that he was kind of immortal. It seemed so sure that he reaches his 100st birthday and that he would always be there. And now, all of a sudden, old age is catching up with him.
It was good to see that he still have his principles (e.g. wearing suit and tie when released from hospital, walking to the car) but there is a bit of mortality in the air that was never there before. I hope for the Queen that he recoveres and is there for a while that she does not have to face the current family crisis on her own.
