Inflation

Aubrey loves to bring me playfood meals and drinks throughout the day. And the pleasure of watching me "eat" the food and tell her how yummy it is has always been enough of a return on the gesture. After I "ate" and returned the cheeseburger she brought me a few minutes ago, though, she just continued standing there. So I asked her if she wanted me to order something else...

"No, pay me a dollar!"
