Priorities

Last week, Margaux and I went to Braum's (regional ice-cream/burger place) to have a malt. While there, I got a gallon of milk. At the checkout line, Margaux surprised the cashier by snatching my wallet from me, pulling out a $20 and saying "money!" As we walked out, I had Margaux (still clutching a dollar bill) in one arm, the milk in the other. Transcript of our conversation follows:

Margaux (looking at gallon of milk): "Milk!"
Dad: "That's right."
Margaux (looking at dollar bill): "Money!"
Dad: "That's right. Which do you like better, milk or money?"
Margaux (long pause): "Money!"
