I remember when tweeting was something birds did.
When social networking meant speaking to someone who might help you up the career ladder as you drank something alcoholic and when, if you needed to buy something, you went to a shop rather than your PC.
Child Number Two has not yet celebrated his second birthday but demands to, 'See! See,' the second a photograph has been snapped.
He is used only to touch-screen and will snub his nose at anything other than a gadget that allows his fingers to dance across its surface.
It's a brave new world, but I do have my reservations about the You-Tube generation and the relentless pace at which news, true and false, moves through the internet.
It was during a moment of contemplation at just how much of an old codger I've become and how far the world seems to have moved in such a short space of time, when Child Number One and I shared a moment.
Number Two had fallen asleep in the car, hair curling with the heat as his body (finally) rested.
The silence was welcome. My ears had been ringing after a couple of hours with a group of nattering, bickering, shrieking kids, much the way they used to in a former life when I stumbled out of blaring nightclubs and into the quiet dawn.
"Remember I wanted a girl?" mused Number One, drawing me sharply back to the present. "Hmm, uh-huh."
"Well, the first minute I saw him in the hospital, do you know what? I loved him."
Almost two years down the line from said date, there is still a catch of surprise in her own observation.
We share a smile and silence falls again as Number One watches the rain teem off the window.
And then she speaks again, a quieter, more contemptuous revelation this time as she glances across at her sibling's snoozing form.
"But I'm still not sharing my Moshi Monsters with him. He slabbers."
And there it is. For all the monumental advances of the last 10 years and amidst the treasure chest of wonder stored neatly away in iPads and iPhones, ready to access at the touch of a button, the basics more or less stay the same.
The world changes, society changes, but kids are kids.
And they don't do sharing.
