I am married to several fine women but they all live in the same body. One of them can place a great emphasis on exactitude. She spooned out two servings of coffee chunks ice cream. She offered one dish to me and then quickly switched offers and reached out with the other. This puzzlement stimulated her interest in exactness. She got out our scale and weighed one serving: 7.50 oz, including the weight of the bowl. She weighed the other dish: 7.50 oz. The same to three digits.
She was satisfied with the scale and the reading. She was indifferent as to which serving I took and which was left for her. I took the bigger one and we are both pleased with our participation and with our partner. Be exact!
