"She was of her own kind and it was a life form old in experience and remarkably astute. It had faced the inevitable a thousand times before and had learned the futility of battering against it head-on. It knew what to do with an immovable object: one climbs over it or burrows under it or sneaks around it. Once uses one’s brains because they are there to be used. Inevitability was not to be feared. That which cannot be stayed must be avoided with skill and ingenuity."
