I was sitting in a local diner this morning having breakfast. There was a family at the table next to me getting ready to pay their bill and leave. The dad was paying with a credit card, but they planned to leave a tip in cash. They didn't have enough paper bills, so the dad pulled some loose change out of his pocket. He pulled out a bunch of recently minted US quarters. The grandmother exclaimed "you can't leave this fake money for the waitress."

The son and the grandson began examining the quarters. The grandmother picked one up and said "look, light as a feather. It's fake." The father and son laughed, and the little boy said " Yaya, that's real money. "

I was tempted to tell the kid to listen to his grandmother, but I thought better of it.
