It was pretty hot when my family was visiting last week, so there were a lot of children requiring cold drinks to sate the thirst resulting from running around like crazy people. My eight-year-old niece appeared in the kitchen requesting ice water, so I pulled out the ice cube trays to fill up a water bottle for her. She took a look at my plastic ice cube tray and said, "Hey, cool."
She had never seen an ice cube tray before.
She lives in Arizona, where almost everyone has a freezer with an ice maker built into it, I suppose. So I showed her how it worked, and she watched with totally unfeigned interest as I twisted it to break the cubes out of their molds, pried them out with my nail, and re-filled the tray at the faucet.
I should have taken her upstairs to show her her great-grandmother's rotary phone, which we use because it doesn't plug into an electrical outlet and thus functions when the power goes out. That really would have blown her mind.
I'm starting to feel old . . .
