Note
I went into orienteering mode on my way home from work. I saw an older couple in the parking garage, and they looked very confused. They kept walking up and down the rows, so, just like I do when I see bewildered young children out in the woods, I went up to them and asked, "Are you okay? Do you know where you are?"
It turns out they were completely lost. In the completely wrong garage...a parallel error. I set them straight and sent them on their way.
