Write a detailed description of a suspenseful scene outside a cliff with grass and roots.
assistant
This ledge feels like it's about to fall off the rock face at any time. Tough grass grows in the soil captured by cracks in the rock, and the roots of the plants pry, very slowly, at the stone, forcing it farther and farther apart. Some day it'll give, and the ledge, and anything -- or any one -- on it will plunge down onto the flatlands below.
