Ordinary everyday things I no longer know how to do

Coastpath I recently treated us to a swanky Sky Glass TV (and it’s navy blue ?)
You literally talk to it and tell it what you want to watch.
After four months I still have to explain to DH how to use it, every single time ?

I use cash regularly, I can pay by phone or card, but I’m aware there are those who can’t so I’m doing my bit to keep cash going for them.
I do most of everything on the internet and am very comfortable with it, zoom for book club, Twitter for news, WhatsApp or Signal for group chats. But I also make phone calls, post cards and use the local butcher and farm shop in person. My iPhone and iPad I consider necessities.

I have no idea what those QR codes are all about.
I can't operate our TV. We have three remotes and I don't know what they all do.
I've only learned how to turn the brightness up on my mobile phone last month when the nice lady at the Albert Hall ticket office showed me how to do it so she could check my ticket.
The new light bulb classifications are beyond me.

The modern technological world is a blur for me.

I am getting unfamiliar with real money; always tapping a card or making a bank transfer so consequently scratching in my car tray for bit of cash for car washes. Even a cup of coffee can be tapped for.

Every job seeker needs a mobile phone these days. Universal Credit is arranged by phone, and the journal has to be kept by phone, so a smart phone is not a luxury.
I am much too old to be a job seeker but I would not want to be without my phone, though I rarely make calls on it. It is also a camera and a torch, as well as a source of information and communication.
I would miss my ipad even more if It broke.
I can do without Netflix, or a tumble drier.

I have started to vaguely but regularly worry that if there was a cyber terrorist attack;
and the internet went down;
I would be well and truly up a certain creek without a paddle

My daughter pays in a shop or restaurant with her watch. She doesn't carry a bank card. I really wouldn't be able to cope with that!
