Money is Theoretical …

Wife: “Ok…we did some review exercises today. He (son, 5) really needs some work with money and size concepts (fewer, more, less, greater, etc.) … From now on, if he goes (out anywhere), he should stand in line and pay with cash. Then sit with him and review the receipt and count his change.

Me: “No problem … money is only a concept, ’til somebody’s taking yours.”
