Stuttering implies Village Idiot
About one hour into the film, Bob, the American soldier, Alison, the land girl,
and some British soldiers are walking around the town at night.
The meet a man and Bob asks the man some questions about the town.
The man stutters but answers the questions.
Bob then asks him "Are you by any chance the village idiot?".
There is nothing else to indicate that the man was an "idiot".
I wonder if there was an attitude or belief in England at the time that
stuttering or a speech impediment was a sign of mental retardation?
If so, this belief may have prompted one prominent Englishman to get help.
