All you #RoyalWatchers have prolly finished your 7th rereading of #Spare, the book by that one that took off to the benighted to become a #HollywoodCelebrity?
Spare has the common meaning of "an object held in reserve in case the one currently performing the task fails".
And I can see how this'd apply to that prince.
But there's another meaning along the lines of "fly off the handle", "storm with rage", "maddened (with anger)".
This feature in the book?
