it sometimes takes you a while to realize that you ARE lost. For the longest time, you can convince yourself that you've just wandered a few feet off the path, that you'll find your way back to the trailhead any moment now. Then night falls again and again, and you still have no idea where you are, and it's time to admit you have bewildered yourself so far off the path that you don't even know from which direction the sun rises anymore.
