Lifestyles are different now and in the main I've adopted a lot of current practice. I shop on line - groceries, clothes, household items. I use my card mostly and just keep £20 in my purse for the odd cash purchase. I embrace the self service tills. I accept that my grandchildren have their own experience of life. They don't like being hauled round shops either, unless it's a toy shop of course.
My mum shopped daily for food and I remember being hauled around the shops and hating it, getting into trouble for hiding in the racks of clothes and picking up and touching things - being so bored. Give me modern shopping habits and next day, or even same day deliveries. I sometimes order my groceries from Morrisons, via Amazon. I order in the morning and I get it late afternoon or early next day.
It's a shame if high streets cannot adapt and are entirely lost. Some are becoming more like social centres with smaller, interesting, unique shops and regular themed street markets.
There is nothing better, for me, than browsing in a book shop or library. I hope there is room in modern life for them.
