you are half a tame horse, half a wild horse. Your owner puts a halter on you and hooks the rope to it. He leads you to the pasture, takes a hammer out of his pocket, sticks the hook into the ground, hooks the loop at the other end of the rope to the hook, hits the hook with a hammer so that you can't pull out the rope without pulling out the hook, and checks if it's solid so you don't run away, and then leaves .
