There once was a man who wanted to discover the meaning of everything. He wandered across the world, searching for someone wise enough to explain to him what all this was about, what was the meaning of everything. After many years, in a distant land, he was told there is one Sage who knows the secret, the meaning of everything. So he traveled to the huge house where the old Sage lived. He knocked at the door, but there was no answer. He tried opening the large wooden door. It was not locked. The traveler entered the house, to find himself in an enormous hall with walls covered in shelves with books. He walked further in and entered a large room also filled with books. He moved to the adjacent room - and discovered that there, too, shelves were everywhere, and on them - only books. He approached one of the shelves and picked up a random volume. He opened it, and inside it, he saw the letter N, filling the pages. The pages of the book were all but rows of NNNNNN... He picked up another book, opened it - the book was filled with TTTTTTT.... He tried another one, and another, and each of them was filled with but one letter. Flabbergasted, the traveler wanted to sit down, when the Sage came in. He was an old, grey-bearded man, just as the fairy-tales have it. "Sir, said the traveler, I don't understand, there is... I don't understand!" The Sage smiled, and replied, "Now all you need to do is connect the letters."
