When I started school at four, I used a pen dipped in ink in an ink well. Who’d have ever foreseen that one day I’d write books on a computer?
When I was four an icecream cost a penny. Now it’s about $4, on the other hand I can buy one with a LOT more than just vanilla flavour.
When I was four we had a cat that ruled the roost… come to think of it, that hasn’t changed at all. But nowadays they do live longer.
