Over the years I have heard tale of Monsters coming around close to humans...in both cases the Monsters didn't want these folks looking them in the face because they knew they were scary ugly...
These tales are about ten years apart without either party knowing the other and in different states...
How did the witnesses know the BFs intention was to hide their ugly mugs? Body language? Psychic message?
How close were the encounters? It seems BFs hide their faces (like peeking) anyway.
I read somewhere/sometime that people/animals are kind of hard-wired to notice eyes/facial features (primarily eyes, if I recall correctly) as some kind of self-preservation early warning system - so hiding a face makes sense.
On a side note: Do Native stories ever touch upon "ugliness"? I always hear/read that the Native tribes respected BFs and described basic features (size, color, etc.). Have never heard anything like, "BF looks like the south end of a north-bound buffalo" - LOL
