Through various turns of events, I found myself on a porch swing in the backyard next-door to my old backyard. John, age 3, was with me. He wanted me to swing higher, but a porch swing isn't the same as a playground swing. He didn't get that. I tried to make conversation, nodding my head toward our old house: "John, there's our old house. You were BORN there!"
And his reply: "How old was I?"
