We were at a school function for Evie, and the kids were singing some songs.

Suddenly an old man tottered to his feet, swaying slowly in front of them. He looked like he was not a day over 200. His back was hunched, his limbs were gnarled. His few remaining hairs were white and wiry, and the top of his head was bald and shiny, long since given way to age spots. He could manage only a shuffling step or two, and looked like he was about to topple.

I clutched Sara’s arm. Was he going to die? Did he lurch to his feet because he was having a heart attack? Would he fall and shatter into a million brittle pieces?

His arm slowly lifted, and you could almost hear the joints creaking beneath the sleeves of his worn suit. Ever so slowly, he extended the arm and…snapped a quick picture with his iPhone.

That’s when Sara and I realized, we truly were the last people on earth without a smart phone.
