Remember all those times you rolled your eyes at your grandparents when they started a sentence, “You know, when I was your age…” ? I had one of those experiences the other day, but in reverse. I felt like I was peering into the future.

I rolled up to a stop light with my window down and noticed that the car next to me was shut off. Just when I was about to ask if they needed a jump, I realized that it was a hybrid, which basically shuts off when it comes to a stop – the engine stops running so it’s completely quiet. It struck me as quite weird – and then I fast-forwarded 30 years or so and imagined myself in this same scenario, but as a grandparent with a grandchild sitting next to me (I guess they were old enough!) Here’s how our conversation went…
Grandchild: “Grandpa, what’s that noise?”
Grandpa: “The car next to us is making that noise because the engine is running.”
Grandchild: “Grandpa, that’s crazy, everyone knows that car engines don’t run when cars are stopped!”
Grandpa (with aged predictability): “You know, when I was your age…”
Grandchild (with youthful predicatability): [rolls eyes]
Grandpa: [smiles with exceeding joy that his grandchild lives in a world where the idea of streets filled with planet-destroying automobiles that all run on non-renewable energy seems just as believable as the idea that one person could own another did when I was their age]
