A bit of a lighthearted one, but here you are:
What is the most amazing thing that your children have (or have access to) that you didn’t?
For me it is definitely YouTube. The entire concept of wondering how your refrigerator works and 10 seconds later watching a complete diagram unfold before you, or an in-depth factory tour… that’s insane when I think of how in my school years we just hoped maybe there was a dusty old VHS with a tour of a crayon factory on it. I don’t love this world of the internet that our children are growing up in, but from art lessons to fascinating science experiments YouTube > catalogues of pricey VHS tapes.
