Okay, but did anyone call them "duties" when you were a kid? The school people who oversaw recess were the duties, and if you got in trouble, you'd get sent to The Wall. Then the other kids would play Wall Ball at that wall and you'd have to dodge the ball for your own safety.
I tell my friends this, and none of them had this experience. They don't know what "duties" are, they don't know wall ball or associate it with punishment. Was this only my childhood?
