When I was young, there was a young man in the area, never went to school when he was a child, so not able to read or write, I believe he was damaged at birth, someone told me many years later. He was good with the farm animals, but rarely communicated with people of any age, and left to himself often tended to wander round, not always fully dressed, and it made some children frightened. There was actually no harm in him, he was generally known as "Silly-----".and I remember hearing an old person say of him: "He's not naughty or nasty, he's simple, and innocent"
-And that was largely what I was basing my interpretation of the entry on. It sounds so much nicer than "idiot", doesn't it?
