Last weekend's lemonade stand was such a success (home made! hand squeezed! made with simple syrup! best in town...) that the kids decided to reprise. Bigger. Better. Three times the number of lemons! They were assisted in this by friendly neighbor having yard sale who invited them to set up in her yard.
The kids have had lots of teachable moments. They are now investment savvy and profit addicted. They understand much about selling consumables (eg: don't pick your nose while making. Absolutely don't pick your nose while selling).
I'd say, based on these two comments, they are now cresting the learning curve.
Me, to Son: Can you get the other pitcher?
Son: Could you? I need to be here, looking cute.
Customer, to Daughter: Here. And keep the change!
Daughter: Oh, we will.
