Not all those who wander are lost.
He who breaks a thing to find out what it is, has left the path of wisdom.
Faithless is he that says farewell when the road darkens.
He had a feeling that the answer was quite different and that he ought to know it, but he could not think of it. He began to get frightened, and that is bad for thinking.
It's a dangerous business, going out your door. You step onto the road, and if you don't keep your feet, theres no knowing where you might be swept off to.
