Just as long as you take care to remember; "In the land of the blind, the one eyed man will probably be executed."
That was the upshot of H. G. Wells' short story "The Country of the Blind": sighted man stumbles into a land of blind people, can't deal with the blind-oriented culture, is derided as insane (crazy guy thinks singing angels are small winged feathered animals that fly, what is he nuts?), his alleged insanity is attributed to these two small damp round things on the front of his head, and he manages to escape before being persuaded to have these round things surgically removed.
