Sounds very much like my 80 year old mother! She’s the only one in her wide circle of friends who uses computers mainly because she worked in admin for the last 20 years of her working life and was trained in using a wide variety of software. However, she doesn’t have a smartphone (signal is very poor at home). Last year, I gave her my old iPad as she needed internet banking to verify purchases online. She has a desktop, a laptop and iPad and is fine 90% of the time. However, little things can flummox her and she then waits until one of her 6 grandchildren calls by! Last month, it was airplane mode that caused a problem.
She’ll be cruising with us this month, on the ship of HER choice, without a smartphone. And that’s how it should be.
