Three hermits sat at the opening to their cave, absorbed in their quiet contemplations.
One day a beautiful bird came by and sang a lovely song.
Five years passed, and then one hermit said, "Did you see that blue bird?"
Five years went by again, and the second hermit said, "It wasn't blue, it was red."
Another five years passed, and the third hermit finally said, "If there's going to be this constant bickering, then I'm moving out!"
