When I was 5 or 6 my grandparents had some friend of theirs drop in during the afternoon. He was stumbling around the kitchen and fell into the frying pan, and my grandparents told me he was blind and couldn't see. Years later I asked my gramma who that blind guy was. She figured out a while later this was some neighbour who had gotten really drunk and been kicked out of his house by his wife. They told me he was blind so I wouldn't know he was so drunk. I never even guessed.
