Zen Master and the Little Boy

I like this quote from Charlie Wilson's War:

There was a little boy. And this boy, at his 14th birthday, gets a horse. And everybody in the village says, "How wonderful, the boy got a horse!" The Zen master says, "We'll see."

Two years later, the boy falls off the horse, breaks his leg and the whole village says, "How terrible!" The Zen master says, "We'll see."

Then a war breaks out and all the young men have to go out and fight, except that this boy can't, because his leg is all messed up, so now everybody in the village says, "How wonderful!"

...You know what the Zen master said.
And the Zen master says 'We'll see.'
