"You'll get lost in the woods! Bears will eat you!" He did get lost, but as long as he was walking he didn't mind. The bears left him alone because he left them alone.
"You'll walk off the edge of the Earth," they cried. He did walk off the edge of the Earth. Drifting in the void, he relished all the walking he had done, but wondered if perhaps he should have turned.
