When you're lost in the woods, sometimes it takes a while to know that you are lost. For the longest time, you can convince yourself that you've just wandered 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 that you have bewildered yourself so far off the path that you don't even know from which direction the sun rises anymore.
