In Kindergarten, I used to believe that when you "borrowed" money, you had to pay back the same coins or bills you borrowed. In the 1960's, milk at school cost a nickel. Sometimes the teacher would suggest that a student who forgot his or her milk money "borrow" a nickel from someone else. But if the nickel went to the cafeteria to pay for the milk, how could you pay the same nickel back to the person you borrowed it from?
