It is deniable, you were plain wrong year after year.
So if I say, mark my words, the Queen looks a bit ragged, she's really slowing down, she'll abdicate this year. Then I keep saying it year after year until she either dies or steps down, would I by right in gloating and saying how right I was that she was declining and that I predicted it?
No, of course not, I'd be a total droning cretin, just like you!
