Hotel minibars are technological marvels. Nowadays they have sensors, so that when someone removes, say, a can of Sprite, the computer at the front desk automatically adds it to the room’s bill. And when the can is restocked, the sensor tells the computer to reset its database.

A toddler is also a marvel, of a different sort. My daughter Carolyn loves repetition. She particularly enjoys opening things, taking something out, and then putting it back. Again, and again, and again.

Put these two marvels together over a long weekend, and what do you get? A minibar bill five pages long.
