So, if you're convinced that particular sequence of PM's is an example of "exception", put it out here so we can discuss just what it is that makes one 'exceptional'.
I tend to agree that PM's are just that, but, as you say, there are always exceptions.
Howsomever (dontcha' like that!) If you accepted cowardly clown's apology, then prolly you shouldn't.
Oh, yeah! G'morning, Fred.
