The kids have been playing store lately with a tray full of play money. Kiran was excited to show me his hanging squash money-holder (which has now been expanded to three squash).
It's been fun listening to the kids haggle over prices, negotiate deals, and set up specials and discount tables. They're taking it extremely seriously, which is mildly unfortunate because when Kiran runs out of money he has a fit.
But even he understands now that if you charge $100 for a block of wood, no one will buy it.
