When my father was a child, he didn't know that postmen had to empty the pillar boxes and take the post to a sorting office etc. He thought that when you put letters through the slot they dropped down onto a conveyor belt which took them to where they were going.
Also, when as children they had to say the Lord's Prayer he couldn't understand why they mustn't let anyone lead them into Thames Station.
