a thought that has never strayed far of late is one of our perception.
take the idea that eyes are the windows to the soul.

now perhaps when we look at someone we are seeing then for who the are. perhaps; but probably not. we create an idea of that someone, often without meaning to or knowledge of it.

then there is the eyes thing.
if we do not know who truly is inside, then perhaps the window is darkened, leaving us mostly with a reflection?
