The children were lined up in the cafeteria

The children were lined up in the cafeteria of a Catholic elementary school for lunch.
At the head of the table was a large pile of apples.
The nun made a note, and posted on the apple tray,
“Take only one. God is watching.”
Moving further along the lunch line, at the other end of the table was a large pile of chocolate chip cookies.
One child whispered to another, “Take all you want.
God is watching the apples.”
