The 16-year-old, attempting to prove to the Golden Weasel that as her older sister she does, in fact, know all there is to know, confidently states the prime interest rate at the close of business (on a Sunday): "C2."
The final exchange rate for the yen against the euro at market close? "Cumulus."
The Golden Weasel looks suitably impressed. The Rose looks at me to see if I'm as proud of her as she deems I should be.
I'm not. I'm twice as proud. Or, as she might put it, "Schrödinger equation."
