Somehow I don't think she was visiting these friends often enough to memorize the layout of their house enough, to be able walk there without her glasses. And she certainly did not memorize the woods across the street, yet we are to believe she managed to walk over a hundred yards in there, during a very dark, cloudy night, without her glasses on. I have quite decent eyesight, comparing to Lisa, yet I was unable to walk through it during a cloudy night without tangling myself into some brushes and smashing into trees. How would Lisa, practically blind without her glasses and BAREFOOT, manage to do that?

This is a pic from the search. Look at that wood. Do you see how thick it is? I cannot imagine myself a practically blind person making their way through these bushes.
