My wife's college friend called her a liar because my wife said she drank raw milk as a child. The "friend" said raw milk would kill you.
I knew a woman who grew up in NYC who thought that ears of corn grew right straight up out of the ground, and that any meat without blue marks on it was probably poisonous.
My cousin, who is reputed to be intelligent, went to see the new lake with me Sunday. We walked across the dam of the 5-acre impoundment, which was built after harvesting a mature forest. None of the logging slash was cleared, since it's intended to be a fishing lake (the bass go in this month). There are saplings and brush showing all in the lake. A few logs had drifted down to the dam, and she asked me if I had put the logs in for the fish to hide under.
Every time I think I've heard the ultimate example of people's alienation from the natural world, something else comes along that tops it. I don't doubt that the person was serious about meat being made in the store.
