They'll be older and mellower, just like all of us. Two out of three of them have seen one of their children die in the intervening period. They can't be carbon copies of themselves back then and we shouldn't really expect them to be.

But they are still here and I hope everyone enjoys the moment. It would be a shame if they are setting themselves up for a slating. But I suspect more of us will revel in the nostalgia than condemn them for giving us the opportunity to do so?
