Well ... that has to be an all time classic !
A tarot reader predicts the future and it doesnt come about ... but "the prediction wasn't wrong; you just decided you didn't want that particular future" and also other people can change it; " Other people have free will, too, of course, so they can change things as well."
But the prediction is not wrong .... seriously ?
That is like saying the weather prediction says sunny ... but some wind came along and blew some clouds in from the ocean and it rained ... but the prediction wasnt wrong ... other forces interfered .
Thats the sort of thing the Australian Government tries to tell us.
