I asked the daughter at the farm house in what way the village idiot is considered one, and in what way his speech does not make sense.
She said he’d say things like, “Fire, forest,” and the listener will have to provide the link.
I immediately said, “Then I’m your village idiot No.2, because that’s the kind of communication I’m capable of in French!”
