You are in a forest on a path. The path proceeds to the north and south. The underbrush to the east is impassable. In all other directions, you see more trees.
There is a wise, old man here. You know he is wise because he is.
The man says, "Hello. I'll follow you as long as you're on this path."
He also says, "Finding q seems to be more dependent on determining important sets than on the layout of the land."
